Has anyone tried this or seen sample code for it? I'm assuming that it would just require using 8 digital outputs, one for each easydriver board, is that right? Are the straight digital outputs adequate for stepping? Seems like people prefer servos for precise control, but I need to control 4 winches which spool out a length of cable to suspend an object in a 3d space.
HELP!
Thanks,
Eric.
I just took a quick look at the easydriver (asuming you mean this: http://www.oceancontrols.com.au/motor_controller/stepper_motor_drivers.htm)
As you say, you need two digital pins to control the stepping and direction of each motor. You can do that with Arduino digital pins just as they are, no problem.
Just remember that the driver board is for bipolar (4 wire) stepper motors only. And 750 mA pr. phase max.
