Hi everyone,

I  brought my old stash alive and found a couple of 18f2550's and
decided to use them instead of throwing them away. I built a very
simple 2 channel 8-bit ADC application and it works  as expected. I
can read the input voltage up to %98 precision which is enough for me
considering the PIC does it all, it does it's job well. Then I decided
to use the circuit as an ohm meter to read input impedance. Input
range is between 0-5V, I attached a 10K pot and connected to a 1.5V
battery to see the voltage change as a play with the pot but there
seems to be no change which doesn't make sense. AN0 is input, I am
sure experienced users on list can find a solution very quickly.

Have a nice sunday!
