No, you cant make a H-bridge in uln2003, instead you can use mosfets
 

Re: ULN2003

Should be possible :

 

Hi,

You can use a micro to directly drive a UNL2003 or UNL2803 which can drive both Uni and Bi Polar stepper motors.
You must however ensure the current and voltage of the ULN2003 and the motor are compatible - put simply it will drive most small hobby type stepper motors on a light load.
