Pulse Width Modulation (PWM) Tutorial

The ‘on/off’ PWM duty cycle: Starts with eight pulses ‘high’ for the first part of the PWM cycle, then finishes with eight ‘low’ pulses for the remainder of the PWM cycle. The ratio of the percent ‘high’ time to the percent ‘low’ time is called the duty cycle.
