Arduino 74HC595 Shift Register using ATmega328P with Proteus Simulation
Introduction Expanding output pins is a common challenge in microcontroller projects, especially when working with LEDs or displays. This project demonstrates how to use 74HC595 shift registers with an Arduino (ATmega328P) to control multiple outputs using only three pins.Using Proteus simulation, this setup visually shows how daisy-chained shift registers can drive LED bars efficiently.This Arduino
