I have been digging around some more, and have re-examined my circuit several times. Embarrassingly, while my circuit was arranged correctly, I had a loose connection that caused the unexpected behavior. I seem to have the circuit working correctly now. If D5 is LOW, the mosfet is ON and the externa...

I am trying to drive the external LED with the 2N7000 using the circuit below. 2n7000.png (Note "muc" --> "mcu" My understanding of ...
