How to Control a DC Motor using Optocouplers with an H-Bridge -- DC to Daylight 18

In this application/project based episode, we're going to put together an H-bridge which will allow us to control the speed and direction of a DC brushed motor. An Arduino will provide the PWM pulses and direction control. We'll also use optocouplers as the interface between the H-bridge and Arduino, which will mitigate noise and potentially dangerous voltages from damaging our IO pins.
