This video shows the tiny NEMA-8 stepper motor for my homemade idle air control valve moving under the control of the Microsquirt. Since a Microsquirt can't control an idle air stepper itself, it's hooked up to an EasyStepper driver controlled by an Arduino that gets the idle air command from the MS over CAN.
