Mind you, even so-called passive devices must either generate a voltage or have a (...) (23 years ago, 31-Mar-01, to lugnet.robotics)

| | | | (...) Actually you don't need LegOS, any input set to raw mode with the LEGO firmware will do fine. This is because even in passive mode there is a pull up of 10k to 5V, and in fact the LED is glowing dimly in this mode. Just tried it, I can get raw (...)

| | | | (...) Yes, this is the result I discovered this weekend. My conclusion is that setting the sensor to raw mode does not fully remove the light produced by the LED, and detrimentally impacts the sensor performance. I think my next approach is to try (...)
