Power advice with only AA batteries

zoomkat:

What about the way to plug it? Directly into the motor shield (or via a breadboard...)

And same question for the power to my Arduino... Do I plug directly the 6 volt into the shield and let the shield power everything so far ? Or there's a circuit that would optimized my ernegical demand?
Thaanx again guys

Good homework assignment. Same basic questions asked/answered daily.

I've been searching a lot and the most frequent answer is to power both of em. Although, I can't find any on with the same power restriction as I have.
