Make this portable soundboard that you can attach to any bike or scooter!

It’s got arcade buttons that playback and mix audio files, so you can honk your horn while playing an engine sound effect.

This project shows of CircuitPython’s audio mixing and looping abilities. The sound effects box plays a background loop of a motorcycle engine and the 3 arcade buttons can be pressed to mix in honking effects.

Powered by the Feather RP2040, this uses an I2S amplifier for outputting high quality audio with a mini speaker.

With CircuitPython, you can easily make audio projects using the built-in audio libraries.

With Audio Mixer, you can play multiple audio files together and output high quality audio over I2S.

With Native USB support, you can drag and drop wave and MP3 audio files like a USB flash drive.

The microcontroller and amplifier are secured to a 3D printed plate that slides into rails built into the case.

These panel mounted arcade buttons press fit and are easy to swap out thanks to the quick connect cables.

A 3D printed clip is secured to the enclosure and can be attached to the frame of any bike or scooter.
