The Pro Trinkets, LEDs and DS1307 RTC arrived. I even got buttons. I have a basic breadboard schematic. I need to assemble the LDS and RTC breakouts and put headers on the trinket.

I will probably develop on my SIK first.

The project path will be:

• assemble parts
• breadboard everything using a SIK
• talk to the RTC, set time, get time, get Unix epoch seconds.
• Talk to LED
• Implement TOTP and perform RFC validations.
• Integrate all of the hardware and software
• Use seconds to generate TOTP
• Space optimize the code
• Magic.
