Bonjour,
j'ai écrit un code en m'inspirant de tuto et exemple pour créer un système télécommandé par infrarouge avec 4 relais pour monter descendre mon lit et mon dossier de lit.
Pourquoi ? Je suis tétraplégique et une fois couché je peux utiliser seulement une télécommande infrarouge et mon fabriquant de lit à arrêté de commercialisé ce produit qui au bout de 10ans a lâché (il en vendait pas assez m'a dit le représentant, sympa hein >:().
Du coup si une âme charitable veux bien me donner son avis sa serai très gentil, car c'est mon 1er programme Arduino alors je loupe certainement des trucs importants !
Comme pour millis();
La doc dit qu'elle revient à 0 après environ 50 jours, alors mon test vous parait bon pour cette éventualité ou elle revient à 0 alors qu'un relai est actif ? La je coupe, l'utilisateur devra relâcher le bouton et appuyer à nouveau, les probabilité que sa arrive sont faible je pense ... ?
Merci d'avance pour votre aide
