This is my first test at driving a stepper motor with an Arduino. I am using a ULN2003A Darlington Array to handle the current requirement of the stepper. This is a simple test spinning the stepper in one direction confirming I properly identified the wire colors to coil relationship.
That chip can handle only 500ma, how did you get it to work with that motor???
