PWM DC Motor Speed Controller
Control the speed and direction of a DC motor with a potentiometer and a MOSFET or driver module.
About this project
A first motor-control project. A potentiometer sets the PWM duty cycle and a MOSFET or L298N driver switches the motor. You learn PWM, flyback protection and how to size a driver for a load.
What it does
- Speed control with PWM
- Direction control (L298N version)
- Flyback protection
- Works with Arduino Uno
Components needed
- Arduino Uno R3 (ATmega328P)
- L298N Dual Motor Driver
- IRLZ44N Logic-Level MOSFET
You can find these parts in our components shop. To learn the skills behind this project, see the ProtoPulse Academy or read our guide on how to write a good electronics project.
