I've been playing a bunch of rhythm games recently, and I feel like I need a metronome to keep time with the beat.
What're your plans and thoughts for entering this competition?

Most of the Science Fair x-in-One kits had a metronome project.

They also had a little kit. It was always the same simple-yet-educational circuit.

My brother and I saved every penny for years to buy this one:

Have the 1976 and 1994 versions
I have the 150-in-ONE too 
This made me go search around the house so I can find the one I got as a birthday present from my parents when I was in elementary school. I just loved going through all of the projects, I was so thrilled when I got it!
