Arduino Tutorial #4 – Digital Pin PWM Output | Arduino …

2020/5/30· Pulse Width Modulation, or PWM, is a technique that is used to get analog results with digital means. This technique is used to create a square wave, a signal switched between on and off. This on-off pattern can simulate voltages in between 5 Volts (ON) and 0 Volts (OFF) by changing the portion of the time the signal spends on versus the time that the signal spends off.

Pulse Width Modulation or PWM for short is a technique for mimicking analog signals using digital output. How does this work? Using a pulse train whose relation D (duty cycle) between time at high level (digital 1, usually 5V) and time at low level (digital 0, 0V) in each period can be modified to produce an average voltage between these two levels:
