🚀 Control Fan Speed with LEDs Using Potentiometer & Transistor!
In this project, we built a 12V fan speed controller using an Arduino UNO, an NPN transistor, and a 5K potentiometer. As you turn the potentiometer: -The fan speed increases or decreases -Different LEDs light up based on speed level -Smooth control with visual feedback 🔧 What You'll Learn: -How to use a transistor to drive a 12V fan -Read ...
