Digital outputs can either go ON or OFF. Analog signals, on the other side, can smoothly assume multiple values in a range. There is a technique that emulates analog behavior with a digital output. That technique is PWM, namely, Pulse Width Modulation. It can be implemented as pulses with varying ‘high’ and ‘low’Read More
