Yeah I have 220ohm on each pin to base. Not sure if this is correct though. I couldn't find what current I need to turn them fully on. So I just used a 220ohm which gives me 22mA.
Wiring is as follows...
Pins 2-5 go to each transistor, which in turn go to to each wire of the stepper. I put the 5V to the two input wires of the motor. It was here that I put the 1ohm resistor, but now that you mention it.. when I did it previously I did do it wrong, so I think I did have a shoot through.
