Hi All, I've just added a new page to my website that describes a non-destructive mod to the light sensor that actually allows it to read ambient light! (URL) The range is <10 for a dark box and >90 for a halogen lamp about 6 feet away. It's really (...) (26 years ago, 28-Mar-99, to lugnet.robotics, lugnet.robotics.rcx.pbforth)

(...) Measuring PWM is not difficult, but it would involve a micro (PIC12C508 anyone?) dedicated to the task and then you would have to get it to drive the RCX, which means motor drivers, etc. If you are willing to spend $50 and LOTS of time, then (...)

(...) I have checked this out, and if you use the standard RCX firmware (or other firmware that uses the RCX ROM, then you get the waveforms you are talking about at 125Hz 1/(1ms x 8). You also get polarity information - oh no, I've said too much. (...) (26 years ago, 26-Mar-99, to lugnet.robotics, lugnet.robotics.rcx.pbforth)
