Ultrasonic sensor help

Using Arduino Sensors
#1

Hello,

I was wondering if I could use a Lego ultrasonic sensor with my Arduino. When used with the NXT it tends to be inaccurate but I was wondering if the Arduino would change that.

Here are some links:

No.

Do you know how I would connect it to the Arduino? The wire that lego uses is just like one that would be used on a landline phone.

Thanks,

The mindstorm system uses an I2C interface running at 3V3, so you need a bit of hardware, then you need to know how to talk to it. There are lots of examples if you google:-
