I'm using an L293D with the standard bipolar stepper library.  When the motor is not in use, I would like to remove the power to its coils.  What is the best way to accomplish this?  I currently have the Arduino VCC directly connected to the driver pins Vcc1, 1,2EN and 3,4EN.  I have a dedicated 12 volt power source connected to driver pin Vcc2.

You can cut the current to the stepper motors by driving the EN inputs to the L293D low. So you need to connect the EN pins to an Arduino digital output pin instead of to Vcc.

Thank you, this is exactly what I was planning to do but wanted to confirm with others.  I'll connect both EN pins to a single digital output.

Thanks again.
