Hi all, firstly my electronic skills are medium and my circuit design skills are almost none.
I have an arduino project to detect 100 light sensors, so my first thought was to use the resistance or voltage checking facility..
But the help I need is about the chained circuit, something like: If each activated LDR in the line bypasses a 100k resister, i could simply measure the total resistance to find out how many sensors are activated (or not activated, i don't mind calculating it backwards)
Here is about as far as i got with my circuit, no idea if i need the 1m ohm resister to make it complete.. can someone help me with this design?
Many thanks!
