weird behaviour with potentiometers
Posted: Sat Dec 04, 2021 7:19 pm
i have connected four potis with each 100k to gpio 12,13,14, 27.
if the potis are full open, wiper at 3.3v i can't upload anything. arduino ide fails to proceed.. if the potis are in the middle or closed, wipers at gnd everything is fine. i tried different poti values first 20k now 100k. same behaviour. is this normal? do i better use higher even values like 500k or more...or is it some to take as given, work with it?
any hints?
