Código:

/*

  Turns on an LED on for one second, then off for one second, repeatedly.

 

  This example code is in the public domain.

 */

 

// Pin 13 has an LED connected on most Arduino boards.

// give it a name:

int buzzer = 13;

// the setup routine runs once when you press reset:

void setup() {                

  // initialize the digital pin as an output.

  pinMode(buzzer, OUTPUT);     

}

// the loop routine runs over and over again forever:

void loop() {

  digitalWrite(buzzer, HIGH);

  delay(100);

  digitalWrite(buzzer,LOW);

  delay(100);
