[TriEmbed] Protection from Dual 12V inputs

[Grawburg]

I've tried this and it doesn't work.  I did change the resistors to 220 just to see if that made a difference.
My actual set-up does not use MOSFETs as I originally asked about but instead uses two DPDT relays.
The input voltage goes through a level shifter since I determined that the 3V3 through the resistor was too close to
the 2V5 that produces an unknown state in the relay modules. So the output from the shifter is 5V which does work fine. I still need to
be able to make sure a bad code doesn't allow both relays to activate.

Ooops, forgot to add base resistors.
