When I hook up 1 LDR sensor it works fine and the readings I get are OK. When I add another 1 or 2 LDR's then their values are random but the first one continues to work.
Can someone point me in the right direction?
The LDR's I'm using are: http://www.maplin.co...-35963?doy=17m7
I've tried various resistor values too.
I'm using firmware version: 4.1.0.6
many thanks
