The project goals are:
- Implement TOTP on a Trinket Pro.
- Retrieve time from a clock source. A DS1307 is the initial choice.
- Use a display to show the generated hash. A .56" LED display is the initial choice. It is 4 digits so the hash will display one half at a time.
- Use a button to generate a hash and display it.
- Successfully generate reference TOTP hashs from the RFC.
- Successfully retrieve time from the RTC
- Successfully display the hash on the LED.
