Hello,
When connecting a LCD display with a potentiometer to Arduino, I noticed that the potentiometer gets warm (it smelled as if it was burning).
Could anyone explain why this is happening? Is it normal for the potentiometer to get a little warm?
I have attached the diagram of how things are connected.
This happens with a 1, 10, and 100k Ohm potentiometer. I checked with a multimeter, and the potentiometers seem to be working well. I also noticed that the brightness change (by varying the resistance) is rather quick. I was expecting a more gradual brightness change.
Thank you for your help!
