Need Help, 1 Pot affecting other pins

#1

Hi all, I am quite new to axoloti and have minor experience in programming and electronics. I was testing my board with 1 potentiometer (10k), but when I tested it, it seems 1 pot will affect another pin parameter.

I am only using 1 pot to PA0 pin. pot connected directly to VDDA and GND. I used female header pin soldered into the board, already tested it with a multimeter and i didn't found any short. am I missing or did something wrong here?

Thankss!

if the other pins are unconnected, the connected pot will influence those pins as well. as soon as you hook up other pots, these inputs will not interact anymore. you can also ground those pins to test...

this applies to most mcus out there since they usually only have one or two adcs that read all the pins... floating pins will fluctuate and will be influenced by other pins as well...
