Let's Make Robots!

Battery Question

Hi all,

I am very new to building robots and don't have much knowledge of electronics, apart from the basics many years ago at school.

However, I got an arduino at the weekend and have started doing experiments with it. I've just managed to take apart a cheap RC toy car and get the arduino to make it go backwards and forwards via a L293D motor driver and a very basic program. There are two motors in the car - the other one is a DC one attached to rack and pinion steering - I've not connected this to the other side of the L239D though yet.
