Blinky, is your first experiment in the world of Arduino. Let's blink! We will connect a LED to pin 13 of Arduino and turn it ON/OFF every second.
Hook Up
Code
/* 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 }
