Clappetiere is a dancing marionette lamp that responds to applause.
The marionette hangs on wires in a black box resembling a theater stage with LED spheres attached at the top. Piezo sensors capture vibrations at three levels of volume triggering the three LEDs to turn on one at a time and the marionette to dance faster. The movements of the marionette are guided by servo motors that connect to an Arduino board.
Opposed to what happens in TV shows, when the audience claps upon request, the interaction reacts to the audience’s applause.
