Led blink (100 pour 2€)void setup() {

// initialize digital pin 13 as an output.

pinMode(13, OUTPUT);

}

// the loop function runs over and over again forever

void loop() {

digitalWrite(13, HIGH); // turn the LED on (HIGH is the voltage level)

delay(1000); // wait for a second

digitalWrite(13, LOW); // turn the LED off by making the voltage LOW

delay(1000); // wait for a second

}

Led FadePulse Width Modulationint led = 9; // the pin that the LED is attached toint brightness = 0; // how bright the LED isint fadeAmount = 5; // how many points to fade the LED by

// the setup routine runs once when you press reset:void setup() { // declare pin 9 to be an output: pinMode(led, OUTPUT);}

// the loop routine runs over and over again forever:void loop() { // set the brightness of pin 9: analogWrite(led, brightness);

// change the brightness for next time through the loop: brightness = brightness + fadeAmount;

// reverse the direction of the fading at the ends of the fade: if (brightness == 0 || brightness == 255) { fadeAmount = -fadeAmount ; } // wait for 30 milliseconds to see the dimming effect delay(30); }
