I'm wondering if this can be done without a mosfet?
I have the following set up and working, the 3v TTUL works because the z-doids but the circuit can be broken at the blue line and that seem like a bad situation to me. That device is not going to take the two 5v pulls well. So I'd rather put some type of a voltage divider in here so that the two can be disconnected. Though I'm trying to achieve this without a mosfet mainly because I'd like to prescribe the fix to a "common" individual and not make it too complicated. If there is no other way, so be it.
This being my divider logic at the moment.
