Hi, I am totlly new at arduino.
Could you let me know how can I connect 3 photo resisters to arduino board (as a picture attached) for reading bright value of each resister ? and source for it ?
Thank you.
What have you found so far?
What didn't it do that you wanted?

No you need a pull up resistor between the analogue input and +5V. This should be about the same value as your photo resistor under medium light.
The other end of each photo resistor should be connected to ground.
