Hi Dennis,
Unfortunately - you can't view the article or code without buying a copy of the original
March 1998 issue #92 from Circuit Cellar. Assuming they even have a copy of an article
that old.
The code would mean very little to you if you're only familiar with BASIC since it was all in
Intel 8749 assembler using the very old Intel ISIS assembler. It was similar to standard 8051
instructions with a few differences due to the old 8749 architecture.
It would hardly be worth buying a copy of that old article if you're only using PICs, and the
schematic for the LDR sensor circuit was essentially the same as what you already have.
Edit: I think Elektor or some other magazine just bought-out Circuit Cellar, so maybe they
now have all rights to old articles? Not sure, but I know Circuit Cellar was bougth-out!
It just turned on/off two very bright LEDs for the headlights. It was a cool project, but
way outdated for now.
The neat part about the robot was it had push-button switches that allowed you to enter
the time to move in certain directions. If you messed it up, you just re-programmed it to
follow a course for specific time periods in fwd, rvs, back, left, right, etc. It didn't have any
sensors to detect obstacles since it was designed as a game - where you would compete
against other users to program the bot to navigate different courses.
It had 2 7-segment LEDs to view program entries. It was really simple, but a ton of fun at
parties. And it was my first article ever published in a major magazine.
Edit: I think Elektor bought Circuit Cellar, so they may now own the rights for old articles?
