PWM Tutorial

In this article, we will learn what is PWM? PWM signals can be used to control motor speed or brightness of led, driving servo motors or to change the amount of power going to any devices. Let’s start with a description of waveforms. Here a wave form of 10Volt looks like You can see 10V and 0V on above figure. If we will create a waveform 10V half of time and 0V half of the time, you can see a waveform some ...
