Sorry probably the wrong term what I meant is the you'll need to bring
down the 12v to either 5v or 3.3v (I'm not sure which voltage) using
and op-amp. Or if it's more digital (0v or 12v) then maybe a
transistor or a zener. Basically you need some simple electronics to
bring it down to acceptable levels so the device can deal with them.
