I'm planning on using a setup like the tutorial http://arduino.cc/en/Reference/Stepper
with a bipolar stepper motor from SparkFun. I want to be able to "turn off" the stepper motor when it's not running. Can I do this by connecting the two ENABLE pins on the H bridge to Arduino pins, and setting them LOW to disable any power going to the motor, saving, heat & power? Or is there a call the will 'Disconnect' the stepper when it's not in use. (it'll only be used 2 times a day for a few seconds).
