dé 1 2 3 4

Ce projet consistait à créer un dispositif qui génère un chiffre entre 1 et 4 à l’aide d’un bouton. En appuyant sur le bouton, les led clignotent puis s’allument aléatoirement. En fonction du chiffre (soit 1 ; 2 ; 3 ou 4), le buzzer émet un son. On peut recommencer en appuyant sur le bouton.
