Bang Bang!! Hacking Switch Controllers to Play Rhythm Games Using...
summary
Builds a homemade taiko drum interface that turns microphone audio into Switch button presses and it works. Uses a Teensy microcontroller with the Teensy audio board, an FFT that samples 1/344 s into 256 float bins (~172 Hz each) to distinguish center (bass) vs rim (treble) hits, and finally hacks a cheap Target controller by wiring a button line to ground to simulate presses. Demonstrates actual code, wiring, and a playable result with modest tuning.
