This project is currently getting started and there aren't many details yet.

    So this project stopped a few weeks ago when I destroyed half the modules due to incorrect wiring. I plan to start over soon with an Arduino Pro Mini and a better power/battery setup!

    Basic timing and displays are working. Next step is actual TOTP and then serial syncing.
