I will have a look at the solar trackers.
I found a site about 4-20mA.

Is this good info that could help me accomplish my function?
Cheers!
A phototransistor yes. After giving this a second thought now with the input i get here. Maybe that would work.
The reason i chose LDR at the beginning was simple, the only thing i knew :)
After thinking about it for a while now i could use photo-diodes or photo-transistors. Im not really after...
By variable resistors you mean a potentiometer? Sorry for being stupid :)
Yes, i have been thinking about that. But a transistor is smaller. What about a galvanic separated output?
I have been trying to find a good way to use photo-transistors. But how do i adjust the sensitivity?
Doesn't the...
Hello there!
I have a project laying around bugging me.
This project is what i think basic. And the function im trying to make is..
I have one LDR used as a refrence.
I also have three other LDR's that i want to use as thresholds for each of the op-amps.
The refrence voltage from the refrence...
