Ultra sonic From the NXT

Using Arduino Sensors
1

How do I connect a LEGO Mindstoms Ultra sonic sensor from LEGO to the arduino?

I think the NXT sensors use I2C -have a look at the Wire library.
You'll need to find the sensor's unique address; I'm guessing it is out there on the Interweb

Sorry i'm new and I have no clue what that means. Does anyone have a how to?

google works for me yes. But I have no clue how to wire the NXT ultra sonic sensor to the arduino or how to read the distance from it. I don't understand those links.

Maybe then, you ought to start from the beginning, and work through some examples and tutorials.
