//Good news, the BOOT button is connected to GPIO0 (which is also a bootstrapping pin to set the boot mode), so pressing it will pull GPIO0 low.

// the setup function runs once when you press reset or power the board

void setup() {

  pinMode(0, INPUT);

  // initialize digital pin 2 as an output.

  pinMode(2, OUTPUT);

}

// the loop function runs over and over again forever

void loop() {

int Push_button_state = digitalRead(0);

if ( Push_button_state == HIGH )

{ 

  digitalWrite(2,LOW ); 

}

else 

{

  digitalWrite(2, HIGH);

}
