An offshoot of nxt-python. Support can be had at the mailing list there.

This project is aimed at NXT control library developers who wish to include support for a given sensor but don't own the hardware. They can use the code here to test-run their implementation using only an nxt, arduino (about $30 if one is not already available), and a modified sensor cable of telephone jack.

The arduino code may also be used as a template for interfacing arduino hardware to an NXT brick to make use of the abundant hardware IO capabilities, though this is not the aim of the project.

For instructions, Checkout the code and see the README. This program is also included in the arduino directory of an nxt-python Working Copy.

Note that currently, only a few sensors are supported so the library will be of limited use. If you have a missing sensor available, it would be appreciated if you could contribute a protocol description file for it!
