Arduino CrossFit Timer

Arduino CrossFit Timer via the Adafruit customer forums.

I was looking for, what I thought, was a simple clock/timer design.  Something with a remote and a big display that could be read from across the gym and that I could program with up/down counting but also intervals specific to CrossFit like Fight Gone Bad or tabatas.  I wanted to incorporate a bell to give it a gym feel and something that could be heard over loud music. This journey took me through many designs, chips, a custom board, wood working and a whole lot of learning!
