- 16. Pulse Width Modulation( PWM ) PWM is form of Analog output. Digital +5V == PWM value of 255 Digital 0 == PWM of value 0 PWM can take values from 0 to 255 PWM is used for varying Control mechanism. Example:1) Create multiple colors using an RGB LED 2) To vary the speed of a motor. PWM can be customised in the programming. 12/19
