After several test I can now use my dualshock 2 with arduino 😀

The problem was the controller. I changed it but I had the same result. And then, when I changed to 5v, miracle, it worked! (the other one was not working on 3v3 or 5v)

Here is the result: http://img23.imageshack.us/img23/2990/worka.png

Sorry for the inconvenience and for my for bad english (I’m from Belgium)

Goodbye 🙂
