Chatière electronique - Arduino Nano LCD RFID Sécurité porte

Chatière éléctronique, produits et premier test

Comment peut on facilement réaliser un projet électronique avec Arduino pour créer une chatière permettant la sortie et l'entrée de votre chat mais pas celui du voisin! Une nouvelle version sera mise à jour bienôt! Objets utilisés pour ce projet:
2 LEDs coloriés.
Lecteur de carte RFID d'induction.
1 servo moteur.
1 carte de dévéloppement Arduino.
1 d'extension ProtoShield.
2 platines d'experimentation.
Des resitences, des cables jump et 1 cable d'alimentation USB.

Produit final, test en ligne
