Hey,
Thanks for the reply. You have misunderstood me, my fault.
If i explain the setup it might become clearer. Basically, I have a power supply that connect to the driver, and the driver has a 5v input for driving steps and direction. The driver powers the motor. What I want to do is to use the Arduino to control the steps / dir of the driver, not directly control the motors. The driver itself handles all the voltage / current to the motors. I suppose what I am asking comes down to this: does the digital out provide 5v or do I have to bring in some sort of transistor and the 5v power line to get a 5v signal?
For your last post I am guessing you do get 5v from the output, but I just want to make doubly sure.
Thanks for replying,
Dave.
