Can an Arduino be used as a controller for this Vexta stepper driver?
Probably, but the input pins are out of focus you photo. Post a better photo of the connectors and we can give a definite answer.
better pic also I have manual in PDF if that helps
Yes, those are fairly simple to control with a Arduino or other microcontroller.
For testing, you can connect a momentary on pushbutton to CW or CCW, and for each push of the button, the motor should move 1 step.
I don't remember if H.OFF should be jumpered, but its in the manual for the driver, so is the correct setup for the small switches.
If you are using it with a Arduino, use some optocouplers to isolate the arduino from the controller, or the arduino will die.
It is more common to find arduino programs that generate a step and a direction signal, rather than the CW CCW of this driver. It should not be hard to program around.
I suspect the driver has an opto built into it. Using an external one as well could make for slow response.
If someone could link to the Arduino (or other) hardware that I need it would be very much appreciated.
