Hello arduino's and arduina's,
I was wondering if i could use a uln2003 driver for a 2 fase stepper motor (http://www.ebay.com/itm/361650624812) and how?
many thanks in advance
The stepper you have referenced is a bipolar stepper which requires a full H-bridge to operate. The ULN2003 driver can be used for unipolar steppers (5 or 6 wire), but cannot drive a 4 wire motor because they require polarity reversal.
Ok thnx
