In this video, I will show you how to build a 3-Inch LED Digital Clock using the PIC16F628A microcontroller. The clock features a large and bright 4-digit seven-segment display, real-time clock functionality using the DS1302, and temperature measurement with the DS18B20 sensor.
The display uses 3-inch common-anode LED modules, driven by 74HC595 shift registers and ULN2003A drivers, resulting in a simple, reliable, and cost-effective design. I will walk you through the PCB assembly process, component installation, power supply verification, and clock setup procedure.
This project is suitable for beginners and electronics enthusiasts who want to learn about PIC microcontrollers, digital clock design, shift registers, real-time clocks, and temperature sensing.
