A CircuitPython USB HID media controller built from an RP2040 board and a rotary encoder. Plug it into any computer and it works instantly as a media keyboard — no drivers required.
Rotate the encoder to raise or lower volume. Press down for play/pause. All pins and timing constants are configurable at the top of `code.py`.
Works on Windows, macOS, Linux, and ChromeOS. The firmware is open source and CC BY-NC 4.0 licensed.
