void setup() {

  pinMode(2, INPUT); //Pin 2 as INPUT

  pinMode(3, OUTPUT); //PIN 3 as OUTPUT

}

void loop() {

  if (digitalRead(2) == HIGH)

  {

  digitalWrite(3, HIGH);   // turn the LED/Buzz ON

  delay(100);                       // wait for 100 msecond 

  digitalWrite(3, LOW);   // turn the LED/Buzz OFF

  delay(100);                       // wait for 100 msecond 

  }
