Bonjour,
Merci pour vos réponse, voici le code que j'ai crée, il permet d'afficher la tension d'une batterie de 12volts via un pont diviseur de tension et l'intensité via un tores à effet hall. J'ai également dessiné deux carré (rouge & vert) afin de simuler deux interrupteurs qui enclenche un relais.
