Beginner

Project guide

Usage

Plug your QT Py into your computer via USB. Then, launch Trombone Champ and pick out your favorite song to play with your newly assembled trombone controller.

To toot, press the arcade button to send a space bar key press. The arcade button's built-in LED will light-up every time its pressed.

Slide the NeoSlider up and down to change the pitch of the trombone in the game. The 3D printed trombone's slide moves much like a real trombone for the full brass section experience minus the spit valve.

Going Further

This project could be adapted as a MIDI controller or other more traditional musical application. You could also use it as inspiration for other custom game controllers or change up the components, code or housing to better suit your needs.
