I have seen a custom sensor with three light sensitive elements and filters. you might be able to build a crude one with one light sensor, one motor(slowed down with worm gear or the micromotor), a wedge belt (...)

| (...) My guess is you would have to use colour filters to get reasonable results. I did toy with that idea for doing a colour photocopier once, but haven't got around to actually testing it yet. The downside is a 3-colour scanner would either use 3 (...) (19 years ago, 27-Jun-05, to lugnet.robotics.rcx, lugnet.robotics.rcx.robolab)

| Hi Just wonder if there is anyone who has attempted to have lego light sensor to distinguish more colors than just black & white. Blue is too close to black... white is too close to white... ---...--- -------- Elizabeth Mabrey (19 years ago, 27-Jun-05, to lugnet.robotics.rcx, lugnet.robotics.rcx.robolab)

| (...) I think you're paying not for the compiler, but for the "programmer" (a sort of serial adapter with an integrated PIC that massages the data somehow). But either way, yes, it's an extra $100 to program the thing. And without the ability to (...) (19 years ago, 23-Jun-05, to lugnet.robotics.rcx, lugnet.robotics.edu, FTX)
