I think I may have blown my ATMega 328 in my Duemilanove but I don't have a second one to verify.
Everything on my prototype breadboard works fine until I attach it to my Arduino. Then a bunch of voltages on my analog inputs drop to zero when they shouldn't - it appears as though they are somehow grounded.
So I removed everything and checked the resistance on my Arduino between my Analog input pins and the ground, and it is showing a resistance (varies from 200 Ohms to 4kOhms depending on which analog pin I am using).
I would have expected that there is normally no path between analog inputs and ground. Is this right, or am I just going crazy?
Would this indicate a blown ATMega 328?
Any help would be great.
