7-segment Mini Clock using PIC16F628A and DS1307 RTC
https://www.electronics-lab.com/7-segment-mini-clock-using-pic16f628a-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 other displays […]

moty22.co.uk has a PIC16F628A based thermometer using DS18B20 digital sensor. Counter based on PIC16F628A . Included C code and circuit diagram. Displays -55 to 125 centigrade. The temperature is read every 15 seconds, can be changed in the code. The math is using integers to calculate the degrees and the tenths of degrees are calculated separately. […]
100MHZ Frequency Counter with PIC16F628A
https://www.electronics-lab.com/100mhz-frequency-counter-with-pic16f628a/
This project shows how to build a very simple yet very useful tool that every DIY enthusiast should have in his lab: a 100MHz+ frequency counter. The schematic is fairly simple and straightforward and uses a PIC16F628A microcontroller for measuring frequency and a high speed comparator for signal amplification and conditioning. The microcontroller uses its internal 4MHz […]
