Bonjour la communauté,

Je bloque sur un bout de code trouvé sur le net.

Je veux adapter ce morceau a un très gros projet de gestion pour un Observatoire.

J'ai beau faire comme le code rien ne fonctionne

Ni les label, ni le Chart ne fonctionnent.

Je peux charger la carte Arduino mais rien malgré les infos présentent dans la console série Arduino

Merci a tous pour votre aide  

Code C~#
