4 Potentiometers with Arduino? Answered
Hey, I'm not understanding something here.
If I hook up a pot (left 9v, middle A0, right GND), I get a varying voltage into pin A0 on Arduino. Then Arduino converts this into whatever.
Well when I hooked up 4 potentiometers parallel to the same battery, and had them on pins A0-A3, none of the pots worked. Whenever I turned one pot, it would change the value for all the others (i was using serial monitor).
How do I correctly hook up four pots to Arduino?
