(...) I've read this tip several times. I experimented with it last night, and the difference between blocking and not blocking the sensor was minimal. My light sensor must not bleed much light directly across. Perhaps I'm doing something wrong? Re: (...) (25 years ago, 1-Jan-00, to lugnet.robotics)
