PWM with 555 timer ic. Best way to control DC motor and lamps.

Title: PWM with 555 Timer | Motor Speed & Lamp Brightness Control

Description:

In this video, I’ll show you a practical PWM (Pulse Width Modulation) controller built using the 555 Timer IC. This project is perfect for controlling the speed of DC motors or adjusting Lamp brightness without wasting power.

You’ll see the complete working circuit, how the components are connected, and a live demo of the PWM signal in action. No microcontrollers—just a simple, effective analog solution using the classic 555 timer.
