This project gives a speed control of DC motor through PWM method. The Dc motor is derived by the L298 driver IC.
You can also control the direction of the motor.
There are three buttons to control the motor. Also a bar graph Led display indicate the speed of the motor.
An proteus simulation file is also available at the download so that you can check the code on your PC.
