Alright, so I'm starting to get a better picture of what I'm going to need, but I have a few basic questions I'm looking to have answered before I continue.
1) What is the difference between unipolar and series wiring? With the 8 leads from the motor, I understand from the stepper info that series wiring is:
Drive A+ = Orange
Drive A- = Black
Drive B+ = Red
Drive B- = Yellow
Connect Orange/White to Black/White (not connected to drive)
Connect Red/White to Yellow/White (not connected to drive)
If that's the case, how would you wire for unipolar?
2) I understand that a motor shield is required, and a Darlington Array chip was suggested. How am I suppose to know which darlington array chip to purchase.
3) The stepper specs say that if I wire the motor for unipolar, it requires 4.5 volts, 2 amps, and 2.3 ohms. It is to my understanding that the arduino board can supply up to 5v when powered by a USB. Is powering the arduino board via the USB enough to power the stepper from the arduino board?
Sorry for so many questions, we've never really dealt with anything like this before. Thanks in advance for the replies!
