// Pin 13 has an LED connected on most Arduino boards.
// give it a name:
int led = 13;    // set the variable “led” to the value 13

// the setup routine runs once when you press reset:
void setup() {
    // initialize the digital pin as an output.
    pinMode(led, OUTPUT);
}

void loop() {
    digitalWrite(led, HIGH);  // turn the LED on
    delay(1000);              // wait for a second
    digitalWrite(led, LOW);   // turn the LED off
    delay(1000);              // wait for a second
}
