En démontant le nunchuk et en retirant le joystick nous pouvons utiliser deux entrées analogiques. Attention la wiimote est alimenté en 3.3v, donc nous sommes limité aux capteurs resistifs qui fonctionnent à cette tension. On utilise ensuite OSCULATOR (sur macOS) pour recevoir les données et les transformer en midi.
