Re: Arduino and LabVIEW
I think I may know the problem - your grounds are not the same. You're powering the arduino off of USB right? Try putting a wire from the arduino ground to the robot's common, and see what happens.
Warning: do not attach robot power to the arduino while the USB cable is connected - you may fry your computer's USB port
Also, you may want to check with your electronics mentor before trying that.. I'm pretty sure it'll be fine though.
