 | | Has anyone figured out how to improve the NXT light sensor?

I'm looking for ways to build this sensor into a studless beam project of mine, and I was wondering, given it's large size and the comparative brightness of the LED used to light it, how can I use it to detect if an object is blocking a path? (...) (19 years ago, 16-Dec-06, to lugnet.robotics.nxt)

The "motor unlimited" is designed to set the motor to run an unlimited distance. It's just a "turn motor on" type block. I think you want the "Motor Degrees" block, or something like that, don't you? (sorry, I don't have access to LV right now) (...) (19 years ago, 15-Dec-06, to lugnet.robotics)
