For a beginner, it appears that there is some conflicting information, so please help me understand. doesn't the pot only control the current? how can that be used to control the voltage
I bought two items. the first based on your recommendation:,
You are saying you are using a poteniometer.
I purchased a 10k ohm trimpot today. Can this work? also can the ground be shared with the ground from the same ground pin from the 5V stuff, or do i have to use a separate ground on the arduino
and a second using a 3.3 volt voltage divider that handles a 2V drop.
how are either of these items to be wired in?
thanks
