DC Motor Speed Control using PWM with PIC Microcontroller

I already posted about Interfacing DC Motor with PIC Microcontroller. In our robotics applications we may have to control the speed of the DC Motor. In this tutorial we will see how to control the speed of a DC Motor using Pulse Width Modulation (PWM). By using PWM we can easily control the average power delivered to a load and by thus we can easily control the speed of the DC Motor. You may think that a va ...
