Greetings!
I have a couple of "newbie" questions if you please:
I ordered from LEGO, their "sensor suite". I managed to wire and
use the touch sensor. But I am puzzled about the use and wiring
of their Light Sensor (9890) and their angle sensor (9891). Can someone
provide me with a short synopsis? Thanks.
I did wire the male header pins onto both, plugged them in the input
ports to see what I was getting. The range of values coming from the
light sensor are 83 (in light pointed directly at it) to 94 (ambient
as well as a finger placed on it). The angle sensor just gave a closed
switch reading (value 1).
While I am at it, what is a convenient (something that involves getting
a part(s) and simple wiring) way to do near range (0-12 inches) distance
sensing off of the handy board?
OK, two more questions:
Can I run the board in tethered mode (so the control program is running
on the MAC)?
The above question is really to also find out if there is a way to control
the board through MAC Common Lisp.
And, finally (!) is there a way to get data back from the board (like large
amounts of numbers) after a run?
Answers to any/all these would be appreciated.
Thanks.
Deepak.

| (...) using the LEGO light and angle sensor is non-trival; custom HW and SW drivers are required. See ftp://cher.media.mit...gosens.txt for details. (...) 0-12 inches is hard, but 0-1 or 2 inches can be done with a simple IR reflectance sensor. See (...) (28 years ago, 11-Jul-96, to lugnet.robotics.handyboard)
