Parpalleig d’un LED amb Arduino

Anem a fer una sèrie de pràctiques sobre arduino. Moltes d’aquestes vene com a exemple dins del mateix programa d’Arduino IDE. Posarem l’esquema de montatge i el codi a programar.

La primera pràctica consisteix en fer que un LED connectat al port de sortida 13 digital faci pampallugues.

L’esquema seria el següent:

Material necessari:

• Un LED

Codi de programa:

I el codi a fer seria el següent:


/*
Blink
Turns on an LED on for one second, then off for one second, repeatedly.

Most Arduinos have an on-board LED you can control. On the Uno and
Leonardo, it is attached to digital pin 13. If you're unsure what
pin the on-board LED is connected to on your Arduino model, check
the documentation at http://arduino.cc

This example code is in the public domain.

// the setup function runs once when you press reset or power the board
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
