In this video, we will see how Arduino analogWrite() function works. PWM stands for Pulse Width Modulation and it is a technique used in controlling the brightness of an LED, speed control of DC motor, controlling a servo motor, or where you have to get analog output with digital means. The PWM signals can be used to control the speed of DC motors and to control the brightness of the LED.
