L’objectif du projet est de créer une table de jeu de rôle conçue pour 4 joueurs, avec une tour à dés rétractable pour chaque joueur. Au centre de la table, il y aura un écran affichant la carte du jeu, et les personnages seront représentés par des tokens physiques que les joueurs pourront placer sur cet écran. Chaque joueur disposera également d’une tablette contenant sa fiche de personnage.

Boite du Arduino

Pour la boîte de rangement, j’ai opté pour une belle boîte en bois provenant de ma grand-mère. Malheureusement, nous avons déjà mangé tous les gâteaux qu’elle contenait !

De plus, il faudra court-circuiter l’alimentation afin qu’elle puisse démarrer sans carte mère.

Je coupe l’alimentation du fils CPU pour le brancher sur le Arduino
