[Uno R3] Stepper motor, LCD, Servo motor.

Bonjour il y a quelques temps j'ai fait une machine à couper le fil de fer avec un Arduino UNO R3 un affichage LCD un pas à pas et un Servo motor.

Je ne suis pas programmeur mais j'ai trouvé quelques codes sur le net, après quelques modifications au code la machine fonctionne bien, cependant je dois ajouter un deuxième stepper avec une vitesse variable différente du premier Stepper, en utilisant un potentiomètre sur l'Analog A5.

Tout les paramètre actuel fonctionne bien, donc aucune modif nécessaire seulement la vitesse du carrousel serais variable, La sortie I12 est disponible pour le pul+ du nouveau Stepper.

J'ai copié les codes ci-dessous afin d'avoir votre commentaire.

Merci
