I found a misc joystick pot today. It was marked with 20k and nothing else. no real information on it.
I hooked it up with:
5v to one side
analog input connected to middle
neg to other side
(only hooked up one axis of the joystick for test)
after a moment or so it started smoking.
i'm new to hardware hacking - i assume i was passing too much power to it? while connected it did give out values though they were a bit low (never hitting 1024 with analogread() as a normal pot would).
should i put some resistors inline?
should it have worked and is just a bad joystick?
all advice appreciated.
