With my current program, I really can't treat it like a broken line, because it's
NOT a broken line. :)
As long as the line is under the row of seven light sensors, the robot knows how it
needs to adjust. When it passes an intersection, the line is still under the other
sensors, so it goes straight. If the line passes under one of the outside sensors,
then is not visible, the robot turns towards that sensor.
I'll still have to think about how I can use what you're suggesting. It's an
interesting idea.
Thanks
