| | | You could mount a printed disk on a comapss needle and use some sort of encoding via the light sensor to determine your direction. By changing the shade from white to black you'd probably be able to get a decent angle reading. The only tricky bit is (...) (26 years ago, 14-Dec-98, to lugnet.robotics)

I know that the Gray Scale does this for linear measurement, but is (...) (26 years ago, 14-Dec-98, to lugnet.robotics)

| | | | I like this idea quite a bit. Instead of going starting white and progressing all 360 degrees to black, though, how about having pure white represent 0 degrees and progressing through gray to black at 180 degrees and then back to white? You would (...) (26 years ago, 14-Dec-98, to lugnet.robotics)
