Using Lego Mindstorms NXT sensors and controllers

I have the Lego NXT set and I'm not really using it anymore, But I still to use the sensors and motors for my Arduino. I need to know how to connect them. Help Please :P Thanks!

Any Ideas on where to get info on this?

It depends on whice sensors you want to use. if your using the touch and light sensors then analog ports but you will have to use i2c for things like accelerometers, and the ultra sonic sensor
