Hello all, I have been lurking for a while, and tried doing a little
searching on the net, and have not seen this anywhere.
Is it possible to use more then 3 standard lego light sensors at a time?
I have seen that there are configurations for light/buttons together,
but I haven't seen anything with stacks of multiple light sensors.
I am using legOS and have done a little experimenting, but just placing
1 ontop of another. These just seems to double my LIGHT variable, and makes
the change VERY small if I am 'over' a line, or not. i.e.
1 light sensor over black = 30's, over white line 60's. which is a nice range.
2 light sensors (stacked) over black = 90-93, over white line = 95,96? This
is WAY to small to be able to assume any accuracy.
Anyone have any thoughts? Tips? Webpages to check.
Thanks for your time.

| An active multiplexor would solve your problem. Take a look at the one sold at www.mindsensors.com, it allows you to hook three sensors to one input port. The sensors can be of any type. They don't work directly with legOS, but I've summited a legOS (...) (23 years ago, 11-Mar-02, to lugnet.robotics)
