Schematics (understanding and drawing them)

[analogoutput]

@Jos

if you would connect a LED !with a series resistor! to the output of this little circuit the potentiometer would than have to be of a type that can conduct the current drawn by the LED. A “normal” potentiometer would not be able to do so.

This is something I did not know. Can you go into some detail? Of course the potentiometer alone would not be safe for the LED, because it can go down to ~0R, but if there’s a series resistor of suitable size, is there still a risk to the potentiometer?
