[Working Code]How to use the L298 Compact Motor Driver

well, couple problems:

  1. The motors are not that big (the GM8's actually)
  2. Meter shows 0v to them

I am suspecting there's something more ... basic ... that I am missing
Am I supposed to ... I dunno... Connect the grounds of the 2 together?
stick that regulated 5V somewhere? (No, not gonna put it THERE)

What should I do next?
