NED STARK

In the thick of Robert’s Rebellion, Ned and his men had been taken by surprise by a group of soldiers that they had no choice but to fight. They managed to win, but staggered their way to your family’s keep, injured and not even fully sure of your family’s loyalties. Given that your father was slain in battle already, you were the Lady of the keep, and you took them in without question. He knew the great risk you were taking, even as you pretended not to know them. He thought about your kindness and bravery long after they left your keep, and he knew he had to repay the debt somehow.

"Had the Targaryens won, Lady Y/N and her family would be put to the sword and their lands taken. I could never forget the risk she took for me."

ROBB STARK

In his youth he’d often avoided Maester Luwin when he was hurt, preferring to brush it off and insist he was fine, but Robb knew this was a serious wound he couldn’t just walk away from. You found him on the battlefield and quickly noticed the infection. Back at his tent, you helped fix the wound properly. When Robb woke up some days later, he had only vague memories of a lovely person watching over him. He tried to get answers, but it seems you had left the camp already. Theon teased the way he was “mooning”, but Robb owed you his life. He just had to meet you properly.

"She left the safety of the camp to find me and then watched over me. No ordinary girl would do that. I owe her so much more than thanks."

SANSA STARK

You both were warned by your fathers to stay inside the safety of the Red Keep, but you were too adventurous for your own good. You talked Sansa into coming with you to explore the markets. Sansa couldn’t refuse you, even if she’d rather stay inside. Everything was fine until you noticed a man following the both of you. When he finally cornered the two of you, you pushed Sansa aside and told her to run. When she found you again, she shook you for being so reckless.

“What happened, what did you do? I was so worried - let’s go back, Y/N, I couldn’t stand it if something happened to you. And you’re a mess! Were you hurt? I’ll look after you myself.”

JON SNOW

You thanked every god that you decided to be thorough that night and do one last sentry round across Castle Black. You heard sounds of a struggle and came running to Jon’s rescue as a dead ranger was upon him. You grabbed it and distracted it enough for Jon to burn the cursed thing. Neither of you could explain what happened, but Jon was quick to grab your arm and breathlessly thank you for coming when you did. You realized he normally wasn’t so forthright, and after that, you two developed a friendship.

“Y/N, I should thank you properly for… that. Whatever it was. You were there just in time.”

BENJEN STARK

It happened during a rangering, when you two were trying to do a routine patrol. Wildlings descending upon you wasn’t anything new, but the blizzard that kicked up wasn’t helping. You lost your horse in the fight, so you guided Benjen’s while he sat behind you, patched up with a makeshift bandage job you had to do in a hurry. It was a frightening night, but you were able to make it back to the Wall. Benjen knew you didn’t want the attention, but he couldn’t help himself relaying the story to his brother and Jon when he visited Winterfell. It was only Ned who knew you were a woman disguising for years as a member of the Night’s Watch.

“I told the Lord Commander what she did, of course, but she’s adamant about keeping it secret. That doesn’t sit well with me, brother. I have to thank her somehow.”

JORY CASSEL

While most ladies were told to stay in their wheelhouses when travelling, your parents knew you liked riding too much, so you often rode beside the guards and chatted with them. Jory always liked your company when he escorted your family to Winterfell. Your escort was attacked by bold kidnappers, and you would’ve stayed out of the way, but you noticed Jory was thrown from his horse. You hastily rode to his attacker and cut the man off his horse, saving Jory from a trampling. Once the kidnappers were fended off, he thanked you right away and wasted no time in telling the others at Winterfell, much to your embarrassment.

“I think you did a great thing, my lady. Most men wouldn’t do the same for me. I suppose I owe you my life, but I wouldn’t want to wish for anymore danger.”

EDD TOLLETT

Cynical as he was, you knew Edd would throw down his life to protect you. The two of you hoped for an uneventful rangering, but the Bear was taking everyone so far from the Wall, that seemed unlikely. When the Others attacked, it was all chaos, and you were cutting through them to protect your Brothers. You didn’t actually find out you saved Edd from nearly getting his head lopped off until he told you afterward. With all the thick fur coats and the harsh wind the Others kicked up, it was hard to see just who you were swinging at.

“You really didn’t notice me struggling with that ugly one? I should count myself lucky your eyes aren’t as bad as Sam’s, love. Wait, you weren’t hurt, right? Let me see that wrist.”

MANCE RAYDER

Back in his ranger days, Mance knew of your disguise and found it amusing to say the least. He always admired your skill and you two were a formidable team when you traveled beyond the Wall. During one of your rangerings, a group of Wildlings descended upon you, and Mance was severely injured from it. You managed to patch what you could and get him back on his horse, guiding both horses back to the Wall. When he left the Night’s Watch, he kept the bright piece of cloth you used to wrap his wound. Mance always kept it on his person, almost like a good luck charm. “This? It’s from a ranger who dragged me half-dead back to the Wall. An old friend who I miss very much. I wonder what sh… what he’s doing now.”

TORMUND GIANTSBANE

You and Tormund made a great team, so you were often on the same missions together. You saved each other’s skin more than a dozen times each, but Tormund was no less excited and grateful each time. The most recent one was when he was grappling with another man on the ground, and you came at them with an axe. Some may have considered that too close, but Tormund was just impressed how accurate you were with the swing. He proudly lifted you up and yelled at the rest of your comrades of what you just did - even if they already saw it - and wanted to tell the camp, too.

“Mance! Come here. Come listen to what my woman did this time. Right between the eyes, cleanest cut I ever saw. Any other man woulda missed, or hacked my nose off. Shoulda brought the head to show ya - ah, why can’t I do that next time, Y/N?”

THEON GREYJOY

Theon grumbled for nearly half an hour that he had it, you didn’t need to get between him and the boar. For one, a girl shouldn’t be handling a boar spear - how did you learn to use it so effectively, anyway? - and secondly, he was just about to shoot an arrow through it. You finally slapped Theon’s back and told him you’d gladly let the next boar get him, because it was only a matter of time before this happened again. Robb was amused by the back and forth, but he tried to be serious. “Theon, one tusk is all it takes for your guts to turn inside out. Y/N saved your life.”

“I know! I heard you the first time. Fine, Y/N, I guess it was… good timing. It won’t happen again, though.”

YARA GREYJOY

It happened during the capture of Deepwood Motte, as you fought alongside Yara and her men. While she was grappling with the weapon of the man in front of her, you saw a Northern soldier pull back his bow. You tackled him to the ground, his arrow went flying way off to the side and you struggled in the dirt with him until you finally cut his throat. As you pulled yourself to your feet, you saw Yara give you an appreciative nod. That night, as she and her men settled into the keep, she gave you a large mug of ale paired with a slap to your back.

"Good work looking out, Y/N. At least someone on this crew uses their head, of course it’d be the other woman. Next fight I’ll have you by my side.”

DAENERYS TARGARYEN

She anticipated her guards to put their lives before her own. She’d seen Jorah and Grey Worm have all manners of close calls, and while it gave her a moment of fear, she knew it was their duty. That’s why you shouldn’t have been doing the same thing. You threw yourself in the middle of the riot, shoving away a man with a sword and kicking away another. Finally an Unsullied handed you a spear and you shoved off several more before grabbing Daenerys and running to safety. Once you two were safe, she pushed you off.

“What were you thinking, Y/N?! You threw yourself right into that crowd - I don’t care if that sword was close to me, you will not endanger yourself on my behalf!”

JORAH MORMONT

Jorah always knew he could rely on you to have his back in a battle, you were more than capable, but he hadn’t expected something like this. Drogo was dead, and his riders were turning against each other. He had to face off three at once, and ended up knocked to his knees by the third one. You rushed forward, killed the rider, pulled Jorah up and shared just a few moments of rest before the fight continued. Dawn finally broke and you two were tending each other’s wounds while Dany took stock of what was left of her khalasar. Jorah wanted you in his arms as soon as possible.

“You shouldn’t have had to fight this battle, my love. The trouble with Drogo, then the witch… I’m just glad you’re safe. It seems I have even more to be grateful for, hm? You’re sure you aren’t hurt anywhere else?”

MISSANDEI

Even if you were rarely in the public eye, and Missandei was not well recognized among the citizens of Meereen, you two still took precautions when going out and enjoying the markets. Your cloaks didn’t protect you from being noticed by a certain assassin, and once you two passed an empty alley, he jumped Missandei first. You were on him at once, throwing him off her with a fury and kicking his weapon away. You used your own to kill him. Missandei was shaken up, and you were quick to comfort her and make sure she was alright before adjusting her cloak and going home. Once you two were in the safety of your room, she wanted to give you several appreciative hugs and kisses.

“You know I am not new to violence, but … It was just so sudden. I was more afraid for your life… Let’s take a guard or two next time, please? Just to be safe. I don’t want you endangering yourself on my behalf.”

GREY WORM

You two finally had leads on the Sons of the Harpy, and like always, you worked as a team. You found a few of their operatives, and chased them through the streets. Once you had them cornered, they fought fiercely, and the last one was dangerously close to landing a dangerous blow on Grey Worm. You got between them, taking the brunt of the damage yourself, and while you collapsed Grey Worm mercilessly ended the man. He carried you back to the Great Pyramid with a speed he didn’t know he had, and waited anxiously while you were treated.

“You took the blow that was mine. You shouldn’t … my life is not worth what your’s is, Y/N. Next time, let it happen to me.”

TYWIN LANNISTER

Having one’s wife involved in the battle plans was not typical, but no one wants going to speak against you to Lord Tywin’s face. You were always present at war councils, and you stayed behind during the battles, listening to reports coming in from scouts. There was concerning news about a large number of Stark troops that were going to provide reinforcements and a surprise attack. You made a decision, using every bit of your influence and your husband’s name to send out troops of your own to deal with them. Several nerve-wracking hours later, you learned the battle was being lost, and the men you sent helped turn it into a proper victory. As the men returned, you were startled by the wound your husband sustained, but he didn’t seem bothered by it. Once you two were alone in his grand war tent, Tywin surprised you by pulling you close to him and kissing your brow.

“My clever little wife. Did anyone try to stop you from sending that battalion? Hm? I’ll hang the next one that speaks out of turn.”

TYRION LANNISTER

You thought his damned sister would have given up after the Battle of Blackwater, but she always seemed ready to ruin the life you and Tyrion made. Luckily, Tyrion had taught you some of her tricks and told you all the men loyal to her. When you began to notice guards changing their patrols and new servants, you did some investigating and found a clumsy assassination plot she cooked up. You dealt with it using your own resources, but you had to tell Tyrion. There may have been something else to her plan. You told him that evening, calmly explaining what you found out and what you did, and you were shocked by how he took your hand and looked so vulnerable.

“You are the sweetest woman the gods could have made. I love you, Y/N … but be careful. Tell me sooner next time. Things aren’t always as they seem with Cersei. I’d tell you I’ll do the rest from here, but I have a feeling that won’t satisfy you.”

JAIME LANNISTER

As much as he changed when he came back from being held prisoner in the North, there were still times when Jaime had that damned Lannister pride. He didn’t like being told to be careful. While you two were travelling to the Riverlands, you were attacked by men still loyal to the North, and you helped Jaime and your guards finish them off. He rounded on you, angry that you put yourself in danger, and you argued back that he needed the help. You even saved him from a blow that came far too close. You two fumed apart for a while, and it wasn’t until several days later that he visited you in the evening. He wrapped his arms around you, careful with his gold hand, and leaned on you.

“Next time just let me take the blow. I mean it. I don’t want anything happening to you because of me, Y/N. I couldn’t live with myself.”

SANDOR CLEGANE

You didn’t usually go this far from the village, but some of your sheep had wandered off and this war meant you couldn’t afford to lose a single one. You were shocked to come across a giant of a man who was battered within an inch of his life. At your insistence, the men of the village helped get him to your house, where you looked after him for several days. Everyone said you were wasting your time, that he was some criminal on the run or he’d surely die anyway. He ended up being disoriented as all hell when he woke up, and he didn’t talk for some time. It was like helping a wild animal. It took several evenings before he finally spoke to you.

“.... You shoulda just left me, girl. Let me die out on those rocks. Would’ve done the world a favor. Did watchin’ sheep get boring, so ya thought to bring in a mangy fuckin’ dog?”

BRONN

The stubbornness of men was astounding, but especially Bronn’s. You and him were coming home from a wild evening at an inn, and while you usually stayed in their best rooms, he had a sudden whim to take you in your room at the Red Keep and nothing was going to stop him. The only thing that kept this stupid plan going is the fact you were just as drunk and agreed to it. Some thief that had no idea who you both were tried to stop you, and Bronn didn’t bother to draw his sword, laughing the man off. You were the one who noticed the dagger gleaming off the moon, and you swiftly knocked the man over with a bottle before he could attempt the attack. That helped sober you up, but Bronn insisted there was no danger.

“What, ‘course I brought my sword. No sense in wasting it on street rats like that. I had it under control, sweet, ya know I did. Still a good hit. Don’t think I’ve seen ya swing like that, remind me to stay on ya good side.”

PETYR BAELISH

While you and Petyr had your little flirtations and secrets - him often underestimating your cleverness and being pleasantly surprised each time - he didn’t expect much from it. He rarely trusted, after all. It’s what led to him being so stunned when he found out you foiled an assassination on attempt on him. It was months ago, and you said nothing, and he had known nothing. Petyr not knowing something for that long was a rare thing, indeed, and it only made him more intrigued. He found himself thinking of you more, and began “chancing” upon you more often in the Red Keep, trying to get your attention.

“Lady Y/N, what a coincidence to see you here, but good timing. Do you recall our conversation some months ago, at the gala for the King’s name day? There’s no need to be so modest about it. I think a lady of your talents is a rare and precious thing, don’t you think?”

STANNIS BARATHEON

You knew your husband was going to face opposition from the Lannisters, but you figured it would be on the battlefield, not through an assassination. You followed the rumors and sent your own men to deal with it. It was troublesome, but you eventually linked the assassin to the Lannisters. You didn’t want to trouble Stannis with such a thing, especially since you’d handled it so quietly. It wasn’t even a week before he barged in your parlor. You weren’t sure what was more startling, his uncharacteristically loud entrance, or how he wrapped you in his arms and pulled you close.

“You should have told me, Y/N, you shouldn’t have done it on your own. If something went wrong, and something happened … They could have easily made you their target, instead. What if it was a trap? Tell me next time …”

DAVOS SEAWORTH

You were very fond of the old knight, so it was a non-issue to help him distribute Stannis’ letters of Joffrey’s illegitimacy. You and your guards helped him through some of the safer land routes, but it wasn’t long before the Lannisters caught wind of what you were doing. One of the Lannister soldiers slipped through your guard, and you shocked Davos when you rode in front of him and parried the man away with your sword, like you had been taught. He was impressed and grateful, and while he told you as much, he still gave some caution about throwing yourself in front of danger like that.

“It’s a good thing ya did, Lady Y/N, I’ll be telling King Stannis about it when I get back … Of course I’m serious. Doesn’t sit right with me for a lady like yourself risking her life.”

MARGAERY TYRELL

After Renly had been killed, there was absolute chaos in his camp. You noticed Margaery through the darkness and hastily pulled her away before two soldiers on warhorses could trample her. They didn’t even seem to care that they nearly killed two ladies. You helped guide her back to her brother and their soldiers, pulling her into the Tyrell wheelhouse yourself. Once she calmed herself from the madness of the night, Margaery couldn’t believe someone would go out of their way to help her like that. You didn’t even come with her, or tell her your family name, so it’s not as though you were expecting a reward. Once she took her place in King’s Landing, she insisted to her grandmother that they find out who you were. She was trying not to let her excitement show when she learned you were in King’s Landing for your own business, and she could finally meet you.

“There’s my knight in silks. What? I think it’s a perfectly appropriate name. There were plenty of so-called men who were content to leave me to die or be captured. I think it’s only right you should get a reward, but before that, we should talk. I have so much I’ve wanted to tell you.”

BRYNDEN TULLY

You were sure that you were in shock, or dreaming, but the soaking wet, exhausted and injured man that turned up on your keep’s gates was right here in front of you. You realized who he was by the armor, and sent your men away while you tended to his wounds through the whole night. It had to be secret that he was here, and that was especially true once morning came and you heard about the “wedding” at the Twins. Just when you entered his room to bring him food and more medicine, he was already getting up and trying to leave. You tried to convince him to stay, that he wasn’t fit for travel, but he was surprisingly firm in spite of his terrible state.

“I owe you more than my life, Lady Y/N, but I can’t stay here. I need to get back to Riverrun, I have to. You’ll be in serious danger, too, if they found out you helped. The less I say and the faster I’m gone, the better.”

EDMURE TULLY

He really thought he was finished on this battlefield, that he’d be lucky to be captured. It seemed he just didn’t have the numbers to take on this number of Lannister soldiers, even if he had strong, capable men on his side. Then reinforcements arrived, seemingly out of nowhere. He wasn’t about to question his good fortune at that moment, but after the battle he pointedly asked the new arrivals who sent them. Back at the camp, he found you, a Lady who convinced her family to support the North and sent troops as fast as she could. Edmure couldn’t help but admire your courage, and insisted you come with him to Riverrun to speak with Robb.

“There’s no need to be modest. You saved us today, Lady Y/N, we would’ve been overrun without the reinforcements. You’ll be my guest, I insist.”

BRIENNE OF TARTH

Brienne had saved your skin more times than you could count, and she always said it was her duty (and because she loved you so much). That was fine and dandy, but you still felt that you owed her in some way. You didn’t want to be the helpless Lady that she was always pulling out of trouble. You got your opportunity sooner than you wanted. A gang of kidnappers took you both off guard in the street, and the last man had gotten a lucky strike. You picked up a rock and struck him hard, and it distracted him enough for Brienne to deliver a finishing blow. He’d seriously hurt her, but her anger and concern took precedence.

“Y/N! What in the seven hells possessed you to pick up a rock - don’t argue, I know it looks bad, but I had it! You should have run! I told you, I had it. … … Yes, fine, it hurts like hell, but that doesn’t mean you can put yourself in danger.”

RAMSAY SNOW

You couldn’t count how many times you told Ramsay that, no, you didn’t want to see how many poor souls he had captured and what he was going to do to them. But sometimes it paid off to humor him for a few minutes, especially if it meant he’d leave you be later on. You hadn’t noticed one of the prisoners had gotten free until he jumped on Ramsay and was fighting with him on the ground. You panicked and picked up one of the candlesticks, hitting the man several times until Ramsay got the upper hand and threw him off. He took the candlestick from you and knocked the man senseless, then tossed it aside, quickly taking your shaking hands into his own bloody ones.

“Y/N, my sweet Y/N, that was very good. You did so well! I knew you loved me. Would you have killed him for me? Hm? I would have liked to see that. He isn’t finished yet, you know.”

ROOSE BOLTON

Not every Lord rode with their men into battle, let alone a Lady, but this was the North and it was in the midst of a war. You were sent by King Robb to bolster Lord Bolton’s numbers, and you got there just in time, in the midst of an ambush. After assisting his men in fending off the Lannister soldiers, you and Lord Bolton were able to dismount and talk properly. He gave you a cordial thanks, speaking to you as if this was the court and not a bloody battlefield, but you didn’t miss the distinct way his cold eyes were glinting in the sun. Even if he didn’t say it, you were sure he was impressed.

“Impeccable timing, Lady Y/N. You’ve done my men and I a great service. Once the camp is established we’ll have a chance to speak properly. It’s a shame it took a war for us to meet.”

OBERYN MARTELL

As dear as Oberyn was to you, you had to admit his temper could be so boyish. There were some men that just made him reach for his dagger, and it was usually the men not knowing how to act properly around his lover. He’d started a huge fight in the brothel as a result, and a much bigger man tackled him to the ground and knocked his dagger from his hand. You hastily grabbed a bottle and knocked it over the man’s head, then kicked him off while he was dazed. Oberyn jumped to his feet, picked you up and hastily got you away from the danger. He didn’t care that he left such a fine dagger behind.

“I knew my sweet Y/N wasn’t such a lamb after all. That was a good swing, my love, a shame about the wine, it was … What? That rat deserved it.”

BERIC DONDARRION

You joined a few Brotherhood scouts and their unusual leader on what was supposed to be scouting and retrieving supplies, but a wrong turn ended up with you all stumbling upon Lannister soldiers. You were shocked at a few reckless moves Beric made, and finally you just had to put yourself between him and a soldier in spite of the weight and power the man had on you. You cut him open well enough, but you were quick to turn on Beric and scold him for being so careless. He did apologize, but you were still fuming at the campfire that evening.

“I’m sorry, Y/N, I’ll say it as many times as you want. You shouldn’t have put yourself in danger like that, especially for a man like me … let me show you why.”

GENDRY

He used to see you as a meddling girl that followed him around too much. That changed when someone’s near-mad horse was frightened and it went tearing through the small cobbled streets. You two surely would’ve been trampled by it, young as you were, and you reacted quickly. You shoved Gendry hard out of the way and cowered down as the horse ran around you. Once he was back up, Gendry shook and scolded you, in disbelief that anyone would bother caring about him like that. Right then he made a promise to protect you, and for years afterward he was always a reliable, protective presence in your life.

“Y/N, remember when I said I’d protect you years ago? ‘Course I still mean it, you just never get into trouble - that’s a good thing! Don’t do somethin’ stupid just ‘cause to see if I’ll come runnin’. You know I will.”

Arduino Lektion 69: OpenWeatherMap Daten auf OLED Display anzeigen

In diesem Tutorial möchte ich beschreiben, wie man Daten von der offenen Schnittstelle OpenWeatherMap.org auf einem OLED Display anzeigt.

Daten für den Standort "Braunschweig" auf dem NodeMCU mit OLED Display von Openweathermap.org Ich nutze dazu den NodeMCU mit 0,96 Zoll OLED Display, dieser Microcontroller wurde mir vom OnlineShop Makershop.de kostenfrei zur Verfügung gestellt. Den NodeMCU mit 0,96Zoll OLED Display kann man für knap 13,75€ unter https://www.makershop.de/plattformen/arduino/nodemcu-oled/ beziehen. Dieses Tutorial sollte jedoch auch mit anderen, baugleichen Microcontrollern (wie zbsp. der Wemos D1 mini mit OLED Display) funktionieren.

Anmelden bei OpenWeatherMap.org

Damit man den Service von OpenWeatherMap.org nutzen kann, muss man sich anmelden. Die Anmeldung ist kostenfrei und schnell erledigt.

OpenWeatherMap - erstellen eines Accounts Nachdem die Daten eingegeben wurden, ist man angemeldet. (Es gibt also kein DoubleOptIn, was sehr fraglich ist.) Unter dem Menüpunkt "API keys" findet man nun den Standard Api key. Welchen wir nun nutzen werden um die Daten von der Schnittstelle abzugreifen. Preise Die Nutzung der Schnittstelle ist im Basispaket kostenlos, jedoch ist die Nutzung dann etwas eingeschränkt. Man kann dann zbsp. "nur" 60 aufrufe pro Minute starten und auch die Verfügbarkeit des Services ist mit 95% gegeben. Weitere Einschränkungen können unter https://openweathermap.org/price eingesehen werden. In meinem Fall reicht das Basispaket völlig aus.

Zugriff auf die API

Für die API gibt es bereits zahlreiche Implementierungen für diverse Sprachen. Leider ist für den Arduino nichts dabei, aber so schwierig ist das ja nicht. Man muss ja nur einen Request an die API senden und erhält ein JSON zurück. Ich nutze neben der Arduino IDE noch zusätzlich das Tool Postman, dieses Tool gibt es als Erweiterung für Google Chrome und als Standalone Lösung. Beispiel Aufruf mit Postman Starten wir zuerst einen Aufruf der API mit dem API key sowie der Stadt Braunschweig. http://api.openweathermap.org/data/2.5/weather?q=Braunschweig,DE&appid=3ee177bfa6d11e51f87055hierfehltnochetwas Als Response erhalten wir im Standardfall einen JSON. { "coord": { "lon": 10.53, "lat": 52.26 }, "weather": , "base": "stations", "main": { "temp": 284.81, "pressure": 1019, "humidity": 58, "temp_min": 284.15, "temp_max": 285.15 }, "visibility": 10000, "wind": { "speed": 2.6, "deg": 210 }, "clouds": { "all": 0 }, "dt": 1538295600, "sys": { "type": 1, "id": 4925, "message": 0.0088, "country": "DE", "sunrise": 1538284651, "sunset": 1538326624 }, "id": 3221017, "name": "Brunswick", "cod": 200 } Diesem JSON Objekt können wir nun zbsp. die Daten für den Sonnenaufgang die aktuelle Windgeschwindigkeit sowie Luftdruck, Luftfeuchtigkeit usw. entnehmen.

Arduino Sketch

erzeugen einer Internetverbindung Wollen wir also loslegen, als erstes schreiben wir unser Sketch das wir in das lokale Netzwerk gelangen und das wir somit Internetzugang haben. Wenn man das Paket "ESP8266 by ESP8266 Community" installiert so sind einige Beispielsketche enthalten.

Paket "esp8266 by ESP8266 Community" Paket "esp8266 by ESP8266 Community" Ich verwende aus diesen Beispielen das Beispiel "BasicHttpClient" als basis für den nachfolgenden Sketch. #include #include #include #include ESP8266WiFiMulti WiFiMulti; const char* SSID = ""; const char* PW = ""; const String url ="http://api.openweathermap.org/data/2.5/weather?q=Braunschweig,DE&appid=3ee177bfa6d11e51hierfehltnochetwas"; void setup() { Serial.begin(115200); Serial.println(); delay(500); WiFiMulti.addAP(SSID, PASSWORD); } void loop() { if((WiFiMulti.run() == WL_CONNECTED)) { HTTPClient http; Serial.println(" begin..."); http.begin(url); Serial.println(" GET..."); int httpCode = http.GET(); if(httpCode > 0) { Serial.printf(" GET... code: %d\n", httpCode); if(httpCode == HTTP_CODE_OK) { String response = http.getString(); Serial.println(response); } } else { Serial.printf(" GET... failed, error: %s\n", http.errorToString(httpCode).c_str()); } http.end(); } delay(10000); } In dem Beispiel habe ich die SSID, das Passwort entfern und den API key entfremdet. Wenn du das Beispiel auf deinem Microcontroller nachstellen möchtest so musst du diese Daten vorher anpassen. Die Ausgabe auf dem seriellen Monitor der Arduino IDE sieht nun wiefolgt aus:

Ausgabe des HTTP Response auf dem seriellen Monitor der Arduino IDE Nachdem wir also das JSON erhalten haben, müssen wir uns "nurnoch" die für uns nützlichen Daten herausziehen. parsen des HTTP Response (JSON Objekt) Für den Zugriff auf die Schlüssel / Wertepaare im JSON Objekt verwende ich nun die Bibliothek von https://arduinojson.org. Des Weiteren erzeuge ich den Quellcode über DEV-C++ IDE welche kostenfrei unter https://sourceforge.net/projects/orwelldevcpp/ heruntergeladen werden kann. installieren der Bibliothek ArduinoJSON Die Bibliothek "ArduinoJson" kann man ganz bequem über den Bibliotheksverwalter der Arduino IDE installiert werden. Dazu navigiert man über das Hauptmenü "Sketch" > "Bibliothek einbinden" > "Bibliotheken verwalten..." es öffnet sich nun ein neues Fenster. Nachdem die Daten fertig geladen wurden (je nach Internet & Rechnergeschwindigkeit kann dieses variieren) wird in der Suchleiste (1) nach "ArduinoJSON" gesucht. Der Eintrag lautet "ArduinoJson by Benoit Blanchon". Gemäß der Entwicklerseite soll man die Version 5 auswählen, daher wähle ich hier die Version 5.13.2 (stand 30.09.2018) (2) und betätige danach die Schaltfläche "Installieren" (3).

Installieren der Bibliothek "ArduinoJSON" in der Arduino IDE Wenn die Bibliothek erfolgreich installiert wurde so steht hinter dem Titel nun die Versionsnummer gefolgt vom Text "INSTALLED".

ArduinoJson erfolgreich installiert Klasse OpenWeatherMap Die Klasse "OpenWeatherMap" enthält die geparsten Daten aus dem JSON der Schnittstelle. Um den Parser zu verwenden muss dieser dem Projekt hinzugefügt werden. Dazu werden die Dateien "openWeatherMapParser.h" sowie "OpenWeatherMap.h" parallel zum Arduino Sketch abgelegt. Ablage der Resourcen Das gesamte Projekt kann vom GitHub Repository https://github.com/StefanDraeger/Arduino-OpenWeatherMap heruntergeladen werden. Dort findest du alle Resourcen zu diesem Projekt.

Drehspulinstrument für Icons

Für die Darstellung der Icons nutze ich ein Drehspulinstrument. Sicherlich könnte man die Icons auch als XBM convertieren und dann auf dem Display anzeigen jedoch finde ich diese Lösung etwas cooler.

Drehspulinstrument Vorder / Rückseite Was wird benötigt? Ich verwende dazu ein Drehspulinstrument mit einer Anzeige für maximal 100µA. Das Drehspulinstrument habe ich bei Wish.com für je 2,70€ erstanden.

Angebot von Drehspulinstrumente auf wish.com Auf der Plattform Wish.com gibt es sicherlich einiges an Schrott und der durchgestrichene Preis ist unter Garantie ein Mondpreis aber mit solchen Artikeln habe ich bisher immer glück gehabt. Der Preis von 3€ ist echt unschlagbar auf ebay.de oder anderen Portalen zahlt mal deutlich mehr (Okay die Lieferzeit wird für den ein oder anderen ein K.O. Kriterium sein.). Des Weiteren wird ein Widerstand von 46kOhm und 30kOhm benötigt und zusätzlich einige Kabel. Der 46kOhm Widerstand wird für den Test der Schaltung am Arduino UNO und der 30kOhm wird für den Live Betrieb mit dem NoceMCU benötigt. Wollen wir zuerst ein kleines Projekt starten um zu testen wie sich das Drehspulinstrument am Arduino UNO verhält. Arduino Sketch Im nachfolgenden Sketch habe ich eine einfache Schleife welche die Zahlen von 0 bis 255 hochzählt und am digitalen PWM Pin 9 ausgibt. Dieses bewirkt das die Nadel des Drehspulinstrumentes sich bewegt. void setup() { Serial.begin(9600); } void loop() { for(int i = 0;isetFont(ArialMT_Plain_16); display->drawString(0, 0, openWeatherMap.getName()); Serial.println("1"); } void windData(OLEDDisplay *display, OLEDDisplayUiState* state, int16_t x, int16_t y) { Serial.println("2a"); Wind wind = openWeatherMap.getWind(); Serial.println("2b"); display->setTextAlignment(TEXT_ALIGN_LEFT); display->setFont(ArialMT_Plain_16); display->drawString(0, 0, "Wind"); display->setFont(ArialMT_Plain_10); display->drawString(0, 16, "Speed:"); String windSpeed = String(wind.getSpeed()); windSpeed += " m/sec"; display->drawString(55, 16, windSpeed); display->drawString(0, 30, "Degree:"); String windDegree = String(wind.getDegree()); windDegree += "°"; display->drawString(55, 30, windDegree); Serial.println("2"); } void weather1Data(OLEDDisplay *display, OLEDDisplayUiState* state, int16_t x, int16_t y) { Main main = openWeatherMap.getMain(); display->setTextAlignment(TEXT_ALIGN_LEFT); display->setFont(ArialMT_Plain_16); display->drawString(0, 0, "Weather"); display->setFont(ArialMT_Plain_10); display->drawString(0, 16, "Temp.:"); String weatherTemp = String(main.getTemp()-273.15,2); weatherTemp += "°C"; display->drawString(63, 16, weatherTemp); String weatherTempMin = String(main.getTempMin()-273.15,2); weatherTempMin += "°C"; display->drawString(0, 30, "min.

Fazit und Ausblick

Wir haben nun die aktuellen Wetterdaten auf dem OLED Display angezeigt, als nächstes können wir nun die letzten 5 Wetterdaten von der Schnittstelle empfangen und anzeigen usw. Das Parsen der Daten mit der Bibliothek ArduinoJSON kann einfacher nicht sein daher konnte dieses Projekt mit relativ wenig Aufwand bewerkstelligt werden einzig war etwas arbeit nötig um das JSON als Objekt darzustellen. Als nächstes werde ich nun ein Gehäuse bauen und ein schönes Plätzchen auf meinem Schreibtisch suchen..... Read the full article
