void setup () {
// Initialize the digital pin as an output.
// Pin 13 has an LED connected on most Arduino boards:
pinMode(13, OUTPUT);
}

void loop () {
digitalWrite(13, HIGH); // set the LED on
delay(2000); // wait for a second
digitalWrite(13, LOW); // set the LED off
delay(2000); // wait for a second
