Bonjour,
J'essaye d'insérer dans mon code un chronomètre mais rien n'y fait...
Le programme est simple :
On lance le programme, et celui ci attend que la boucle soit lancée.
On appuie sur le bouton, la boucle démarre avec, allumage de toutes les cibles, puis le logiciel attend de détecter un changement de valeur sur les capteurs piezo.
S'il y a détection, la cible s’éteint, et ainsi de suite pour toutes les cibles.
Quand toutes les cibles sont éteint, la partie est terminée.
Mon chrono doit démarrer après un temps "x" une fois que le bouton de départ soit déclenché.
Et il doit s'arrêter à l'extinction de la dernière cible.
Vous trouverez dedans des bouts de code d'un topic de 2011, car oui j'ai cherché ^^
Ne faites pas attention à la plupart des serial.Print(), ils sont là pour tester mon programme sans avoir fait tout le montage.
J'attends les capteurs piezo 
Merci d'avance pour votre aide !
