ESP8266(Arduino) interface with Firebase:

  

Aim:
 Make such application in which LED can be control from mobile or website from any remote location where internet connectivity is available.

Requirement:
1 ) ESP8266-E12 WiFi module as shown in picture. You can get start and setup it with help of this post.
2) Download and install firebase-arduino-master  library in Arduino IDE.
3) Need gmail account for create Firebase project.

Step 1:
Go to https://console.firebase.google.com and create new project.

Step 2:
Click on Database now you will see the host name show in image
 

Copy that host name and past in Arduino code given below at line
 #define FIREBASE_HOST "fir-app-example.firebaseio.com"

Step 3:
Go to Setting>Project Setting>SERVICE ACCOUNTS>DATABASE Secretes.
Copy "Database Secrets" Shown in below image

 

Copy and paste Database Secrets at the line in code 
#define FIREBASE_AUTH "examplesd2asdasdasdasd2asd3asd2asd2as32das3d2as2da3" 

Step 6 :
Change line with your WiFi router name and password
#define WIFI_SSID "Wifi Router Name"
#define WIFI_PASSWORD "Router Password"

Step 5:
Download following code in arduino

#include
#include

// Set these to run example.
#define FIREBASE_HOST "fir-app-example.firebaseio.com"
#define FIREBASE_AUTH "examplesd2asdasdasdasd2asd3asd2asd2as32das3d2as2da3"
#define WIFI_SSID "Wifi Router Name"
#define WIFI_PASSWORD "Router Password"

#define LED 2

void setup() {

  pinMode(LED,OUTPUT);
  digitalWrite(LED,0);
 
  Serial.begin(9600);
 
  WiFi.begin(WIFI_SSID, WIFI_PASSWORD);
  Serial.print("connecting");
  while (WiFi.status() != WL_CONNECTED) {
    Serial.print(".");
    delay(500);
  }
  Serial.println();
  Serial.print("connected: ");
  Serial.println(WiFi.localIP());
 
  Firebase.begin(FIREBASE_HOST, FIREBASE_AUTH);

  Firebase.setInt("LEDStatus",0);
}

void loop() {
  if(Firebase.getInt("LEDStatus"))
  { 
    digitalWrite(LED,HIGH);
  }
  else
  {
    digitalWrite(LED,LOW);
  }
  if (Firebase.failed())  // Check for errors
 {
      Serial.print("setting /number failed:");
      Serial.println(Firebase.error()); 
      return;
  } 
  delay(1000);
}

Step 6:
After reseting ESP8266check serial terminal whether the ESP is get connected with your router and got IP adress.
you can now see the new variable created in database. 


Step 7:  
Double click "LEDStatus" and edit it to 1. instantly (its depends on your internet connection) LED on ESP 8266 module get Turn off.

Step 8: 
If you have knowledge of Android you can create App for control LED from mobile. You need to read Firebase documentation and integration methods.

I created my android app for controlling LED from mobile. As Firebase can be assess from world wide so you have end to end IoT application.

For any question comment below. Thank You.

Program ESP8266 WiFi module with Arduino IDE: The Arduino IDE software (short for Integrated Development Environment) is the foundation of what has made the Arduino platform so successful. With it, Makers can program a wide range of compatible microcontroller boards using Arduino’s relatively approachable programming language. Behind the scenes, the IDE software translates your instructions into a more complex code required for your board’s specific chip. Aside from generally cleaning up a number of known bugs, the new update introduces a number of new tools and features. One of the useful feature is board manager which allow use to add customized and diffrent board support in Arduino IDE. In this tutorial we are going to add ESP8266 board in Arduino IDE and program it without and programmer simple using RX, TX pin. Required : 1) ESP8266 2) Arduino UNO 3)connecting wires 4) Local wifi router Step 1 : For buy ESP8266 module here amezon link is given Buy ES...

Fetch and parse JSON on ESP8266 wifi module : Use case:  I want monitor particular json stored on server which can be modify by website from remote distance. It can be useful where you can modify control bits from website and change GPIO status at ESP8266 side. 1) Home automation 2) Information parsing 3) Staus monitoring 4) non realtime notification This system work on principle on monitoring files. Feature :   Stand alone operation of ESP8266.   Uses JSON parsing so data extraction is very easy. Required : 1)ESP8266 2)Arduino or any USB to serial converter with 3.3v or 5v power connection pin out. Basic Working:     ESP8266 :  It uses the local router to connect internet and fetch JSON from server using HTTP get request after every second parse it and display JSON variables on serial monitor(you can compare them and change GPIO for device control). Shown in diagram it send GET request at server and server send back HEADER + ...
