Kurt emailed: "We haven't spent a lot of time working with light sensor calibration yet. Once you calibrate the light sensor, how long does it stay calibrated? For the duration of the program, until the NXT is turned off, until you recalibrate it? To put it another way, if we use multiple programs to accomplish the missions in an FLL competition, can we just calibrate the light sensor before we begin the first program, or do we have to calibrate it at the beginning of each program?"
Great question... anyone have a definitive answer?
