I wanted to make a clock for my brother as a gift, but he is not into any kind of technology. This is why I needed a new design that allows adjusting the time on the Arduino and the displays without the use of a PC or anything else.

For this, I used Nema 17 23mm motors and a custom PCB. We have two buttons to adjust the time. The display shows the time set on the RTC. Then, you can manually adjust the time on the seven-segment displays according to the RTC time.

Data:

Unter STL/CAD Download findet sie die Gerberdatei für die Custom PCB sowie die BOM und PickandpLace für die Bestellung bei JLCPCB sowie den Code für den Arduino Nano
