I'm going to connect 12 potentiometers (100k) to a couple of cd4051 analogue (8->1) multiplexers and to 2 of Arduino (Uno) analogue pins.
Now I think each pot draws 0.5mA (I'm going to measure it to be sure) so around 6mA for all 12 pots. I think it is ok the Arduino permits 200mA as I know.
Also I read that it is recommended to use 10k potentiometers (because of the ADC) but I have also read that the 100k are going to work.
So is there anything I miss here? (before soldering all the power and ground terminals). (the multiplexer in the schematic is a single module)
