Hey,
There are a couple ground pin on the Arduino. I had my easydriver hooked up to the ground on the digital pins and that worked fine, and now ive hooked it up to the ground next to the 5v power, and im getting troubles.
I can't hook it back up to the digital pin to see if some things broken, so i was wondering does all grounds work as a ground, or are there ground for certain purposes?
Hope that makes sense!
