Analog Pins in the Arduino boards work on the principle of PWM. What is the full form of PWM? Correct Answer Pulse Width Modulation

Since perfect analog waveforms can’t be achieved on a digital circuit, Pulse Width Modulation is used to create pseudo analog waveforms by varying the “ON” and “OFF” time of a pulse continuously hence creating a series of pulses whose “width” can be modified according to the need of the user. Here “width” refers to the “ON” time of the pulse. Hence the name Pulse Width Modulation.
