Analog inputs

Do the analog inputs only handle 5 volts max? Can it take a 12 volt signal?
Yes, it can take 12 volt signal, but can only measure 0..5V.
It's okay if you want to use it as the switch (Active high switch).
You may notice subtle changes in voltage on unconnected analog inputs. If this is a problem for you, you can always connect 12V through a resistor.
