| Matthew's program takes one reading at initialization time to determine a baseline value. Any reading that falls 7 units below this is assumed to be a dark line. I take a somewhat more conservative approach, taking 10 readings over one second and (...) (25 years ago, 15-Jul-99, to lugnet.robotics.rcx)
