In this application-based episode on optocouplers, Derek puts together an H-bridge circuit, 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. He also uses optocouplers as the interface between the H-bridge and Arduino, which will mitigate noise and potentially dangerous voltages from damaging our IO pins.
