I bought over 250 momentary buttons by mistake (two pin, 5 mm, SPST). I can't return them. Any cool, fun, interesting and/or very easy Arduino project ideas I can do with as many of these buttons as possible?? I have a little bit of everything in terms of LEDs, motors, sensors and shields - just no creativity LOL. I also have kids under the age of six, so anything that they can interact with is a plus.
What do they look like?
Make a piano out of it. 88 buttons for the 88 keys.

Crossroads has a board that allows you to light 64 LEDs with the SPI bus.
