Uploaded program to Arduino but won't do anything.

I have a Ardumoto, an Uno, a bluetooth slave and magician chassis set up like in this guy's tutorial: Building an Arduino Robot, Part IV: A (Not So) Basic Robot Firmware - miguelgrinberg.com. I'm using BlueStick and it won't budge when I tell it to move. Here is the program: GitHub - miguelgrinberg/michelino at v0.3

Start with the basics:

Is the Arduino powered up?
Is it running the sketch you think it is?
Is it receiving inputs correctly?
Is it trying to take the right actions in response?
Are its actions having the intended effect?

I haven't followed those links to see the code you're running, but on a project like this I would expect to provide debug output so that it is possible to confirm that things are working. Maybe your code already has this, but if not you will need to add it. This presupposes that you understand the design of the code. If you don't, you're pretty much wasting your time trying to debug it.

I've changed the program a bit and now the motor lights are on but the motors don't move. So I'm thinking to make a new program based on this one to move the motors. I'll respond when I get back home.
