I wrote a function to monitor the analog inputs. My approach was similar to the discrete inputs because it used an array to record the values, but I also created a couple of arrays that would send a bit high if there was a change in the reading. One went high if the value increased, and another to detect lowering.

When I measured these potentiometers before, I saw they were logarithmic, but I wanted linear. I assumed I could use a calculation to counteract the scaling, but that turned out to be a lot harder than I imagined. The issue became apparent when I plotted the analog value to the screen as a small rectangle racing along the screen's side, and it would not track the position as near as I hoped. I tried applying the natural log, log base ten, exponents, inverses, and simple arithmetic, but I could not make it behave linearly.
