Since my Arduino motor shield died for unknown reasons and the Mr. Basic controller still wasn't working, I was officially stuck. I posted a question in the forums, and Simon Z pointed to Polulu and gave me some extra info on controllers. After looking at Polulu's catalog, I saw that most of them were out of my budget and making a controller is out of the question because there are NO suppliers in my country. So now I'm stuck, again. I could buy parts on the internet, but the shipping is always a problem. For exaple, I was looking at the L298 motor controller from Solarbotics.
