(...) There was a TV show on the Discovery Channel or one of the other science channels a couple of years back on exactly this topic. It was one of the "kids do science things" type of show.

| | Datalogging with the NXT
|
|
OK, I've got to admit that this isn't exactly "robotics". In fact, it must be about the smallest "robot" I've ever made, in that it was really just the NXT and a single sensor, with a few 3L pins and a studless beam to secure the sensor. But the (...) (17 years ago, 31-Oct-07, to lugnet.robotics)

(...) The changes between 1.03 and 1.04 are far more extensive than the changes from 1.04 and 1.05, if you lump the support for ADPCM compression into a single change (which involves c_sound.c, d_sound.c, d_sound.h, d_sound.r, d_sound_adpcm.r, and (...)

(...) I'm not sure if there's a better way, and I haven't tried it with an NXT, but I've had good luck with option 2 using an RCX.
