Bon en fait, y'a un truc pas clair...

Exemple fourni avec le soft/* 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://www.arduino.cc This example code is in the public domain. modified 8 May 2014 by Scott Fitzgerald */ // 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 }la led onboard clignote, si j'en plug une à moi entre le GND et le pin 13, elle clignote en même temps que sa copine

Je me dis tiens, on va essayer avec deux leds en alternance :/* 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.

alors je me dis que vu que les pins 2 à 13 sont "PWM" je vais prendre un digital, le 53 est juste à coté d'un GND donc c'est un bon choix/* Blink Turns on an LED on for one second, then off for one second, repeatedly.
