Hi, my MOSFET switch is always on. I need it to switch 12 V power on and off with the signal from an Atmega328P-PU pin. I have attached a diagram of the circuit. Can someone see what's wrong? Thank you!

Only if you also have a PFET.could something similar to this circuit be used with the NFET?
Not that I can think of.Is there a way to isolate the DC-DC converter?
The only difference is that the LED can use a low-side switch (N-MOSFET source connected to ground with the LED connected to the drain and going to V+).But apparently switching the 12V battery-converter-camera is different from switching, say, an LED (which I think works with an N-channel MOSFET)?
No, the leakage of either type of MOSFET is negligible for your purposes.Would the P-channel design leak more current?
