I BUILT Binary Clock With Arduino & Shift Register | NO RTC

Want to build a binary clock using Arduino without any RTC module? In this video, I’ll show you how to create a simple yet powerful project using the Arduino Uno and the 74HC595 shift register IC. Instead of using external modules, we use millis() to track time and display seconds in binary format using LEDs. This project is perfect for beginners and also helps you understand deeper embedded concepts like bit manipulation, serial-to-parallel communication, and non-blocking timing.
