L'objectif est de réaliser une borne d'arcade complète (joystick/boutons + interface pc + système de jeu). Pour plus d'informations sur ce projet, contacter louis.

J'ai déjà — en mon nom (louis) propre — acheté des composants (arduino + joysticks + arduino).

J'ai « volé » des fils en cave ainsi que du sapin.

La planche avec les boutons (dont joysticks) sont montés.
