I was wondering the required electronics to control a 2-phase stepping motor, model ph265-05-a6 by Vexta, 1.4V - 3.8A. It has two connections, one marked as THDM -m1op by winchester electronics and the other is a four wire connection. I have no idea what I need or how to control it as I have just used the motor that came in the standard Arduino package. However, I'd like to work on projects with a little more power.
Any help is appreciated.
