Adjustable DC Motor Speed Controller | Simple and Effective

Описание: In this video, I’ll show you how to make a simple DC motor speed controller using a single D882 transistor, a 10k potentiometer, and a 3.7V battery. This easy circuit lets you smoothly control the motor speed without using any IC or microcontroller. Perfect for small DIY electronics projects and beginners who want to understand how transistor-based control works.

Components Used:

D882 NPN Transistor

10k Potentiometer

DC Motor

3.7V Battery (18650 cell)

Wires and Breadboard

💡 Adjust the potentiometer and watch the motor speed change instantly!
