Built a primitive TOTP generator with Python and an Arduino Uno. It generates a code given the current time and a seed value, and displays said code on an LCD screen on the Arduino. It's been confirmed to work with a basic CLI-based login script, but I wonder how I can expand it to be more useful, because at this stage, it's little more than an extended display.
The code and circuit diagram are available here:
