Why PWM is Better Than a Potentiometer for LED Dimming – 555 Timer PWM Demo"
Description:
Not all LED dimming methods are the same! In this video, I explain why using a normal potentiometer to dim LEDs isn't efficient and why PWM (Pulse Width Modulation) is the better solution.
I also demonstrate how to generate a PWM signal using a 555 timer, showing a practical build of an LED dimming circuit that works efficiently. While I didn't build a potentiometer-based dimmer, I break down why it wastes power and doesn't work well for LED control.
💡 What You'll Learn:
✅ Why using a potentiometer alone isn’t ideal for dimming LEDs
✅ How PWM works and why it's the better choice
✅ How to build a PWM signal generator using a 4X5 timer
