I do not know how to connect this pin, which one is ground, vcc, data, and why so many colouuur???
Any heeelp?
Can I use this stepper motor in Arduino?
Measure the resistance between each wire to determine the coil setup.
It might be the 2 green wires are commons to the other wires,
If so they would then be connected together, see Jason2548 link.
Ok look at this one. It is for unipolar two phase motor. I have two of this motors sitting in front of me and I looks to be the same wiring just different colors. instead of green i have reds in the middle.
