Stepper motor Help :)

Postby Jollybox » Mon Sep 02, 2013 11:37 am

I have my stepper motors, I have my Pi - Now I would like to know how to 'marry' the two together... The end plan/result that I am after is a motorised rail for timelapse photo sequences. I would like the Pi to control the motors and trigger the shutter on my camera. eg move n-mm, pause for n-seconds, trigger shutter n-times - repeat... A friend has started writing the python for me (he is a whizz with all things python). I would like to know how to correctly wire the motors to the Pi. I have a photo of the '?control board that came with the motors.

There seems to be a jumper over the pins VCC & VM. The only thing I think I might know is that pin GND is the ground pin...

Any and all help is truly appreciated
