Kit sketches (5)

The Arduino code is based on both a simple "knock sensor" with a piezo element (here we use laminated piezo film) and the generation of a tone, outputting to the speaker (in this case, the sound exciters).

In this prototype, the Arduino generates a 100KH tone whenever a pulse is detected.
