(...) Hi :) (...)

| | Shutting off illumination LED on Light Sensor for LIDAR
|
|
Has anyone successfully found a way (short of paint, or cutting internal wiring) of shutting off the red 'supply light' LED on the Lego light sensor? The supply LED is great for active-detection situations, like line-following, when you need to (...) (24 years ago, 28-Mar-01, to lugnet.robotics)

This sounds very cool. If you want to do the mapping at the bottom, you will have to use alternitive firmware anyway (right?), and they have a passivate command that turns off the light. It passivates the sensor, but I don't think standard firmware (...) (24 years ago, 28-Mar-01, to lugnet.robotics)

(...) Maybe. I think RCX2 with NQC has some crude arrays, I haven't looked into them yet, but I might be able to use them to do simple mapping on the RCX. Or something even cruder if I don't have arrays. (...) Ahh. Hmm. I wonder what it actually (...) (24 years ago, 28-Mar-01, to lugnet.robotics)

Hi Chris, You can turn off the LED with software though you may be a little disappointed with the light sensitivity. The reason the LED is on is because your program has set the sensor to an active sensor. If you set the type to NONE make the mode (...) (24 years ago, 28-Mar-01, to lugnet.robotics)

To make a passive light sensor, you can use a design like Michael Gasperi's: (URL) costs only a couple bucks, and works quite well. If you would like better response from your lego light sensor, you can use a piece of black shrinkwrap tubing and (...) (24 years ago, 28-Mar-01, to lugnet.robotics)
