use 18f14k22 RA0 to read a voltage from my 7805 output via a potentialmeter ( 0 to 5V) .
I found that the voltage input will stay at few hundred mili volt from the POT 0 to almost full, then i can see a quick change in voltage input raise to 5V for the last small portion of POT. (POT used 100, 1K, 10K)
I try to use a power supply to connect to my RA0 pin and the voltage will raise accordingly when i tune up the power supply, no problem..
