I'm using a POT as an input for an ATtiny-based project, where the POT is read by ADC to give me an input value. My question is: What's the best POT (max) resistance for that type of use? I would think greater resistance would be somewhat better as it would be less of a power draw. But I wonder if at higher resistance the signal is less stable in that the ADC circuitry could throw it off in the way a ~10k pull-up resister can be overwhelmed. That concern is just an intuition, I've not seen anything to suggest it's something to worry about.
To be clear, I'm the POT as a voltage divider: attaching one side of the POT to Vcc, the other side to Gnd, and the swiper to the ADC input pin.
