This Arduino code is designed to detect button presses using a piezo sensor connected to analog pin A0. The code includes a debounce mechanism to prevent false positives and can be easily extended ...

Piezo discs have been around since the 1970s, and such cheap (and easy-to-handle) discs are widely used by avid electronic hobbyists and experimenting musicians all over the world. A piezo disk ...
