Use a rpi pico and push buttons to send key strokes to a computer. Utiliser un [raspberry pi pico](https://www.raspberrypi.com/products/raspberry-pi-pico/) et des bouttons d'arcade pour simuler des touches de clavier.
This is the companion project to the [Stopi](/arthus/stopi) stop-motion software. Ce projet est le compagnon de [Stopi2](/arthus/stopi2).
## Software setup ## Installation
1. Upload 'code.py' and the 'lib' folder to the rpi pico Copier le fichier 'code.py' et le répertoire 'lib' à la base du pico.
2. Done
## Hadware setup ## Matériel nécessaire
* 5 push buttons * 5 bouttons poussoirs
* 1 ON/OFF switch with indicator light or a separate LED * 1 switch ON/OFF avec une LED intégrée ou en supplément.
* 1 330Ω resistor * 1 rsistance 330Ω
