Line Following Sensors

Hello everyone,

I am making a line following robot for a competition in Australia called "Robocup Junior". It involves following a line, also, taking shortucts indicated by a green square. At the suggestion of one of the friendly LMRians I invested in an IR Sensor board that can follow the line perfectly. The only problem I have been having is that white and green have the same readings (must be a problem with infra-RED and GREEN being different, or something:)

So I am creating this thread to see if anyone has had any experience with any light or colour (color) sensors.

AXE 045 RGB sensor


 Does anyone around here have any experience with the AXE045 RGB-sensor from Picaxe? I connected it to my Picaxe 28X1 microcontroller and I am only able to get readings from about max 40 for red and blue, green only gets to one or, if I shine directly into the lens with a flashlight, up to 9.

 Any help?
