This is a scoring machine built using an Arduino Uno (ATMega328P-PU). It works pretty great, and we've used it at club practices for a few weeks, and had no issues.
Epee works 100%. Foil works 100%. Saber needs whipover and better timing, so 75%.
Main code needs a good refactor, but it works!

We need the new arduino toolkit
git clone git@github.com:arduino-cmake/Arduino-CMake-NG.git
Do not install avrdude from the repos, we need the one in the arduino toolkit. This gets pulled in automatically by arduino-cmake.
