How do you calibrate the light sensor?
This is our first year with FLL. I am confused about how to calibrate the robot. In fact Iím not even sure what that means. For now our team is trying to build a line follower program and itís going beserk so Iím wondering if I should start with trying to understand the concept of calibration.
For now we go into the viewing sensor of the Mindstorms brick and choose the reflected light and look at the number that pops up whenever the light sensor is on top of something white or black. This seems to work ok, but Iíve been through the nxt tutorial on ortop.org and there it gives you a program to run in order to calibrate your robot and seems to say not to use the program on the brick. Whatís the difference? The tutorial mentions something about the viewing sensor giving the absolute light value. Iím not sure I understand whatís wrong with that.
Then I also thought I read somewhere that once you calibrated your light sensor with a program, you couldnít use the viewing sensor anymore to get your numbers. What does this all mean?
