ps3 controller input

I’d like to connect my ps3 controller to my arduino with the USB cable. Is this possible? I assume there’s got to be a library out there…

You'll need a USB host shield. The CircuitsAtHome shield has a PS3 controller library.

And where would I find a schematic for such a shield?

By following the Schematic link on the first link I posted?

Oh, there it is. It was broken before.
