It adjusts the output pulse width to regulate the average output voltage. The output voltage of a PWM signal is determined by the duty cycle, with 100% duty cycle corresponding to the full operating voltage. PWM allows microcontrollers to output analog values between 0V and 5V.5 Sources

Pulse-width modulation (PWM), also known as pulse-duration modulation (PDM) or pulse-length modulation (PLM), is any method of representing a signal as a rectangular wave with a varying duty cycle (and for some methods also a varying period). PWM is useful for controlling the average power or … See more
The term duty cycle describes the proportion of 'on' time to the regular interval or 'period' of time; a low duty cycle corresponds to low power, because the power is off for most … See more
