Multiplexing 7 Segment displays with Arduino and Shift Registers

This guide will explain the basics of controlling multiple 7 segment displays using an Arduino and a couple of shift registers. This project is ideal for displaying numerical data or managing a set of LEDs. As a beginner, like me, I had no clue on how to tackle this task. After trying out different methods
