In this video I discussed about 7-segment display project with Arduino and 74HC595 shift register IC, but with a twist most people miss.
There is a pin on the IC called OE (Output Enable) that usually gets ignored, but it can actually control the brightness of the display. In this video, I’ll walk you through the whole setup - counting down from 9 to 0.

Code: https://drive.google.com/file/d/17iXl...

📌 What you’ll learn in this video:
✅ How to check which display is common cathode and common anode
✅ How to wire a 7 segment display with Arduino (common anode and common cathode)
✅ How to use the 74HC595 shift register (DS, SHCP, STCP, MR, OE pins explained)
✅ How to write Arduino code for countdown on 7-segment
✅ How to use OE pin to control brightness of segment LEDs
