The contents of this repo mirror the structure of the Arduino project directory. Dependencies are included in the libraries/ folder. For the time-of-day mode switching timers to work, you'll need to copy the contents of this directory into your Arduino build location for libraries. That's usually just {your Arduino homedir}/libraries.
Arduino Pro or Pro Mini (config included) ATMega328P (5V, 16 MHz)
