I just had a look at the new stepper motor library page ( by Tom Igoe, and I have a question about motor wiring.

I did a circuit using bipolar stepper motors (5 wires, with no reference, bought in Seoul) and ULN2003 chipsets. It works, but uses 4 pins on the arduino.

According to the example circuits shown on the tutorial page, I wonder if it is possible to control the motors using only 2 pins on the arduino. Should I use a L293D bridge like on the schematics?

Thanks for your help...
