Arduino Shift Register Tutorial | 74HC595 LED Binary Counter
In this video, I show how to use the 74HC595 shift register with Arduino by building a binary counter that controls 8 LEDs using only three Arduino pins. The 74HC595 makes it easy to expand outputs, and this project is a simple way to understand how data is sent through a shift register.
I go through the wiring, the code, and how the bits move through the register to create a clean LED sequence. If you're experimenting with Arduino electronics , working on 74HC595 projects , or just want to learn how shift registers work, this tutorial will help you get started quickly.
