Bonjour il y a quelque temps j'ai fabriqué une machine coupe fil de fer avec un Arduino UNO R3 un afficheur et un Stepper

Je ne suis pas un programmeur mais j'ai trouvé des codes sur le net, après quelque modification au code la machine fonctionne bien cependant j'ai besoin d'ajouter un deuxième stepper avec une vitesse variable différente du premier, a l'aide d'un potentiomètre sur l'Analog A5.

La sortie I12 est disponible pour les pul+ du nouveau Stepper.

Je met les Codes plus bas affin d'avoir vos commentaire.

Merci

Mike
