Subject: Re: Analog ports....
Cause I was wondering how well it works. To my understanding, analog
phototransistors' outputs depend on intensity. I found that variations in
the colors of surfaces reflect differently. i.e. black reflects much less
than white in the IR spectrum. I was thinking that maybe you're using a
different device that measures "true" distance, like an optical
triangulator or something.
