## Pulse Width Modulation
Pulse Width Modulation (PWM) is essentially a way for digital circuits to pretend to be analog. Essentially, analog circuits can produce signals that have gentle sweeping curves, elegant waves, like God creating the feminine. Digital circuits can only produce on or off values - hard square shapes with sharp edges, like man chiseling facts into stone.
