I finished building the Pop'n Music controller and use Arduino Leonardo. My question is how do I make the button light up?
The button comes with [email protected] watts and I'm not sure how to build a circuit for it.

Gas and a match.

Use lights. This is why you should learn stuff yourself and not just use kids and blindly follow the instructions.

What I usually do is power the lights with a 12V adapter and split off a separate rail that I step down to 5V to power my Amtel IC. That's probably the easiest way of going about it. Also, I do believe the Arduino can be powered by 12V directly.
