I wonder, is there a plug socket that breaks the existing connection between the pull-down while creating a new connection?
Unfortunately, whatever resistor I use the connections effect each other.
Your solution of shorting it out will only result in you not getting the right value the first time you take the reading although you might miss this.
Are they any better or reliable than the external ones?
I guess if I add a short delay, it would should be all right.
I've tried 1 ohm t
