https://dumblebots.com/2019/04/09/arduino-basics-exploring-pwm/
WEBApr 9, 2019 · PWM, which stands for Pulse Width Modulation, is a technique used to convert digital voltages to apparent analog voltages. A microcontroller is a digital device that can normally output either 0v or 5v (some microcontrollers may use 3.3v). Consequently, any devices they power can either be switched off or on, even if …
