We have explained pwm in this tutorial using 2 examples which will help you learn how to control led brightness using pwm and how to control dc motor speed using pwm.
General description on dc motor speed control of dc motor using pwm circuit and excitation table firmware for generating pwm. Pulse width modulation or familiarly known as pwm is used to control the delivered power to load without loosing the efficiency. A more efficient way to proceed is by using pulse width modulation technique to control the speed of our dc motor. If you are new to electronics we have a detailed article explaining pulse width modulation.
