Tutorial 4: Pulse Width Modulation (PWM)

Welcome to Tutorial 4! This tutorial explains how to control the brightness of an LED using Pulse Width Modulation (PWM). By adjusting the duty cycle of the PWM signal, you can vary the LED's brightness. PWM is also used to control the speed of DC motors like fans, or RC car motors and generate tones.
