I'm using the drv8825 stepper motor driver and a battery pack of 8 alkaline AA batteries giving off 12 V. I can't find out how many amps it gives off, but seems to be somewhere between 2400-3200 mAh.
The arduino is also plugged into my laptop for power.
Thanks for all the help, I've attached my drawing for you.
