- /*
- Blink a LED
- Turns on an LED on for one second, then off for one second, repeatedly.
- */
- // Pin 13 has an LED connected on most Arduino boards.
- // give it a name:
- int led = 13;
- // the setup routine runs once when you press reset:
- void setup() {
- // initialize the digital pin as an output.
- pinMode(led, OUTPUT);
- }
- // the loop routine runs over and over again forever:
- void loop() {
- digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level)
- delay(1000); // wait for a second
- digitalWrite(led, LOW); // turn the LED off by making the voltage LOW
- delay(1000); // wait for a second
- }
