aide pour programmation afficheur 7 segment

International Français
1

bonjour

mon projet est de réaliser un afficheur de prix avec des digit 7 segments ( photo)

je possède un impriment 3D pour la réalisation de la boite

je peut aussi réaliser des circuit imprimé

le problème reste la programmation car j'arrive a bidouiller un peut pour afficher des numéro

la ou sa se complique est qu'il faut un bouton pour sélectionner des prix déjà pré enregistre

ps: je débute dans l'arduino

n’hésitez pas a me posé vos question merci d'avance

commencez par lire comment utiliser le forum puis, pour bien débuter avec l'arduino, un bon point de départ c'est de lire les tutos d'eskimon
