s3c2410 development platform, using the potentiometer adjustment system voltage, when the voltage rises, the DC motor speed real-time to improve immediately. When the voltage is highest when the speed reaches 100 rpm. When the voltage drop, the DC motor speed is then reduced time, when the voltage is zero, the DC motor stops. LED light on the real-time display of the current speed of DC motor.
