TELEGRAM WITH RASPBERRY PI

In this video I will show you that how you can connect IFTTT with Raspberry Pi and whenever you send message from your phone chat to raspberry pi and the LED connected to raspberry pi will glow.

STEPS TO DO IT

First you need to open terminal on your raspberry pi and write the following command:-

bash <( curl -sL https://particle.io/install-pi ) After writing it press enter. Then after few seconds it will ask you for an email, password and aname for your raspberry pi to setup an account. Then after setting it up you would have to open build.particle.io  on your computer and sign in with the account you created on your raspberry pi terminal.
Now an IDE will be opened like this :-

After this copy the code given below and paste in the IDE :-

void setup() {
   
  pinMode(D2,OUTPUT);

  digitalWrite(D2,LOW);
 
  Particle.subscribe("your_code", myHandler);//change your_code with a unique code of your wish


}
void loop() {
}

void myHandler(const char *event, const char *data)
{
 
  if (strcmp(data,"led-off")==0) {
    digitalWrite(D2,LOW);
  
  }
    else if (strcmp(data,"led-blink")==0) {
    digitalWrite(D2,HIGH);
   delay(1000);
   digitalWrite(D2,LOW);
   delay(1000);
  }
  else if (strcmp(data,"led-on")==0) {
 
    digitalWrite(D2,HIGH);
  
  }
}

NOTE: DON'T FORGET TO CHANGE your_code with any unique code that do not match with anyone else

After this flash the  code into your raspberry pi by clicking the flash icon located at left.
So with it wirelessly code gets flashed in raspberry pi.
