PWM (Pulse Width Modulation) Interface

Pulse-width modulation (PWM) is the technique that allows to produce variable analog signals using digital means. The average value of the output signal is controlled by switching the digital signal between HIGH (1) and LOW (0) states at a fast rate. The longer the digital signal is in the HIGH state compared to LOW state periods, the higher the output analog signal voltage.

PWM signals are used in a wide variety of control applications. You can use them to control the power supplied to electrical devices like DC motors, valves, pumps, hydraulics and other mechanical parts.
