Firebase Integrate With ESP8266

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.

Go to firebase console and create new project

https://console.firebase.google.com/?pli=1

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"

Go to Setting>Project Setting>SERVICE ACCOUNTS>DATABASE Secretes.
Copy "Database Secrets" Shown in above image.

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

Change line with your WiFi router name and password

#define WIFI_SSID "Wifi Router Name"
#define WIFI_PASSWORD "Router Password"

#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);

}

After reseting ESP8266check serial terminal whether the ESP is get connected with your router and got IP adress.
Goto https://console.firebase.google.com/project/fir-app-9adb8/database/data you can now see the new variable created in database.

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

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.
