IOT with Firebase : Control Led from Firebase using Arduino Node MCU ESP8266

[@muhdfikri4709]

Easy to follow and it works like a charm! good job

[@Resiloreid]

When only testing the connection using firebase path, secret code and then wifi and password, the sketch was able to compile just fine. But when I added the code for LED from your video, I'm getting the error "error compiling to board nodemcu 1.0". Why is that? I've tried almost all the ArduinoJson library with no luck. Please answer this, I'm really desperate.

I'm having a problem getting data from Firebase with my nodeMCU. At first, it connects and is able to send and receive data just fine. But after losing connection and reconnecting several times, it stops receiving data from firebase, though it is still able to send data to firebase. What could cause this?

[@aadhikarianish]

Thank you so much for making this video :) It worked for me.

Hello, when I ran a Arduino-to-Firebase project, i got mistake as following: C:\Users\USER\Documents\Arduino\libraries\firebase-arduino-master\src/FirebaseArduino.h:20:18: fatal error: string: No such file or directory #include --- I use Arduino IDE 1.8.5 version, and when I google why it got wrong, someone said "firebase library is made for 1.6.9 version." But, I have tried, I failed, please help me, thank u !

Hi, I want ask, how to send json data to path on firebase ?

[@rahulmoorkoth2395]

Waiting for your next tutorial.. to control with app😊

[@djoleluk]

I did everything that you explained, the code is successfully uploaded to my WeMos D1 R1 ESP8266 board but i just keep getting 0 value on my Firebase.getInt("child_name") function in the loop() function. Even if i change this value in the database. And i am quite certain i set up the firebase well since i can change my value there with my android app. Wifi is on i checked it with condition if (WiFi.status() == WL_CONNECTED) in the loop function. Just getting the value from firebase in my Arduino code is problematic. Am i missing something while calling Firebase get functions, or maybe I'm not connected to the firebase. Can you give me some advice please, i would be grateful. And yes one more thing, when i upload full test sketch Firebase_Demo_ESP8266 changing only FIREBASE_HOST, FIREBASE_AUTH,WIFI_SSID and WIFI_PASSWORD i get the message printed on my serial monitor "setting /message failed:" which i guess comes from the activated if condition inside the loop method that evaluate Firebase.failed() function to true and the loop function returns. Maybe this information can be helpful too.

Hi, I have a problem, it only changes the state of the application to Firebase, but from Firebase to the Nodemcu card, the relay cannot be activated, do you know how to solve it?

[@kashishnaqvi4708]

Hey, Is there any way we can build an app with MIT app inventor for different nodemcu boards, as we always have to add the firebase token and url in Firedatabase properties, we always have to edit it then compile the project, Can you please tell me if i can fill the token and url of firebase from outside the code? Please help, it is urgent.

Haii.. I just saw your video and might help me a little. Can I ask, you use " Firebase.getInt("led_status") " for getting data number (0 and 1). If my data is text like "led on", what code should I use to get into arduino ide? Thanks before 🙏

[@bytive]

Firebase.setString()/Firebase.getString()

[@faishalriza3139]

@@bytive on the void setup, you use Firebase.set(led_status, 0). Do I have to use it too if the data is text?

Yes, you can you that also

hello, when i want to create a project like you.when i create the project then it take some Analytics location and Cloud Firestore location .so what should i give to it?mainly firestore location.please help me.

i think nodemcu doesn't support firestore you link firebase with firestore and make relevant changes

so what kind of board you used?

Why do i experience disconnecting and reconnecting in wifi?

[@xSoShi]

i have a problem, it says my D1 was not declared in this scope, the last digitalWrite(D1, LOW);

[@bytive]

actually nodemcu uses gpio pins try this: int d1= 5; // d1 = gpio 5 Arduino now use pinMode(d1, output) void loop { digitalWrite(d1, LOW); } for more info about gpio refer: www.google.co.in/search?q=nodemcu+pin+diagram&oq=node&aqs=chrome.1.69i59l2j69i57j69i65l2j69i59.2414j0j7&client=ms-android-xiaomi&sourceid=chrome-mobile&ie=UTF-8#imgrc=47r_W2A31iOr9M:

Once you click 'upload' the code gets deployed on NodeMCU. So the code keeps runnings 24/7 on NodeMCU?

[@bytive]

yes if power is on, void loop() in code run for 24/7

[@vijayalakshmim5302]

HACK ANONS thanks for the reply. If it runs 24/7 Will nodeMCU not get heated up or get affected.

[@bytive]

no there will be no issue just supply 5v, i already using arduino uno on some project which is 24/7 running from last 4 months

No wasim, actually using ardunio we create prototype once prototype product is ready then it's send for fabrication of production. Fsbrication makes that prototype smaller according to your requirements

That library is no longer working now. Use Firebase ESP8266 instead: github.com/mobizt/Firebase-ESP8266

[@sonmai3526]

Update: the library didn't work because Google changed SSL Fingerprint and the library didn't adapt. The author just update library so you can retry!
