I wonder how accurate the AtoD converter in the ATmega168 is, or if it needs any sort of calibration.

So the recorded reading is a full 5V.
Is there some way am I wiring this thing wrong?
Thanks for the quick responses. I'm coming from the coding side of all of this and it's very interesting to see how the code works at such a low level with actual results.
