Pulse Width Modulation Motor Driver

Pulse width modulation (PWM) is a commonly used to for motor speed control. Instead of constant DC voltage, PWM speed control technique uses pulse voltage to drive the motor. The motor speed is controlled by varying the pulse duty cycle. 100% duty cycle is the maximum speed and 0% duty cycle the motor is stopped.
