Re-live your Roland 808 drum machine dreams with these step switches with LEDs. They're tactile, they're momentary, and they're awesome.

This guide shows how you can use them as simple inputs for an Arduino or CircuitPython-based project on Pico, but you can use these methods for any microcontroller board you like.
