Current situtation above.
Problem: LED is on only when resistance is under 50k.
Question: Which variables, or other things should I note when creating circuits like this?
How should I solve the problem so the LED is off @ maximum resistance, otherwise 1% - 100% on?
In other words, I have a sensor (here: potentiometer), which varies in its resistance. I would like to indicate the value with the LED.
Seems easy enough, but in practice, it requires some understanding I'm missing
