getting data from Lego light sensor.

Hi,

Does anyone know how to interface with the active sensor; Lego light sensor??

Thanks!

I believe that it just needs the correct voltage whatever that may be, and it just varies the resistance based upon the light levels. I remember back in the day, there were guides on wiring multiple switches using resistors and then setting the input as a light sensor.

Actually That is not Correct ^, The LIGHT_SENSOR_MODE is set for the switch arrays because its powered .
Here’s The schematic page of the light Sensor http://www.extremenxt.com/light.htm
And heres a good site for interfacing lego sensors with a uController http://www.seattlerobotics.org/encoder/200403/barello/LEGO%20sensors.html
