How To Make Motor Speed Control Circuit | Using NE555 | PWM | Step By Step

In this video, I’ll show you how to build a DC motor speed controller using the NE555 timer IC. With just a few basic components — resistors, capacitors, diodes, and a MOSFET — you can create a smooth PWM speed control circuit for your motor. I’ll also explain the internal working principle of the NE555: the comparators, the flip-flop, and how the timing capacitor charges and discharges to create oscillations. At the end, we’ll test the circuit in action to see how changing the duty cycle affects the motor speed. 👉 If you love DIY electronics projects, don’t forget to like, subscribe, and turn on notifications!
