How to build a simple PWM DC Motor Speed Controller using ATmega8 microcontroller, MOSFET and POT
Please comment if you tried building this!
Here I show how to build a circuit to control the speed of a motor using PWM. PWM is highly efficient in doing this job. It can be used to control very high current motor which much energy loss.
Refer to this video for programming:
Here's the pwm8.hex file to program ATmega8:
