(...) I'd guess it depends on what you are doing. Without a doubt, raw gives you the best sensor resolution. I'd guess that for kids it is easier to think in terms of 0 to 100%. Since you are not a kid, raw is probably better. (...) Kevin (21 years ago, 15-Apr-04, to lugnet.robotics.rcx)

| | Differences between Raw Sensor readings and Light Sensor

Hi, Can someone point out the differences between setting a sensor as Light (or any custom sensor) vs setting the sensor as Raw? Isnt it better to use the RAW readings since it reports a range of 0 to 1023 as opposed to scaling the readings to 0 to (...) (21 years ago, 14-Apr-04, to lugnet.robotics.rcx)
