7-segment Mini Clock using PIC16F628A and DS1307 RTC

This is a minimal and small clock based on PIC16F628A microcontroller and DS1307 RTC IC. It is able to only show the time on a small 7-segment display with a total of 4 segments. The display we used is a 0.28″ SR440281N RED common cathode display bought from LCSC.com, but you can use...
