On Paper: PWM (Pulse width Modulation) Brief Description

PWM is a digital way of outputting a specific voltage between the top and bottom voltages (i.e. 5v to 0v). The output would be a pulse within a period of time. The percentage of the width of the pulse relates to the output voltage. This pulse width percentage is called duty cycle. For instance, within this period of time, if the pulse is at 5v for half of the period of time, then the output voltage is 2.5v.
