Thanks for your feedback! Indeed, kids could learn the real pyrography by using this 'coffe-graphy', the hand movements should be pretty similar to those used with an engraver. It would be useful to fix the small wood stick in a pen-like holder to make the process of drawing more comfortable.

My point was to make a device that allow you to create colour music manually, it's nothing to do with microcontrollers

You might be interested to replace the 'clap' feature with the 'blow out' feature. Imagine 2 contacts made of copper foil that are placed inside the candle's body face to a hole. You blow into the hole, the contacts close, which provokes a 'reset' impulse, then the contacts return to their initial position because of elasticity. The candle goes OFF, you'll have to turn it ON again with the switch.
