How to Use Pulse Width Modulation on the Arduino
Pulse Width Modulation or PWM is a technique used to vary the width of the pulses in a periodic waveform while keeping the frequency constant. This modulation method is widely used in various applications such as controlling the speed of motors, regulating the brightness of LEDs, generating analog voltage levels, and more. In this tutorial, we will explore Pulse Width Modulation (PWM), and how to use it to control the brightness of an LED.
