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.
