Le gant rythmique

Le but du projet du gant rythmique était de créer un gant où chaque doigt, en se touchant, permettraient de créer de la musique à l’aide d’un logiciel de MAO type Ableton.

Dans un premier temps, nous avons réalisé des capteurs de pressions en tissu permettant de générer l’interaction du bout des doigts pour ensuite rattacher les valeurs obtenus à arduino, puis à ableton.
