Resolve the noise in the rotary input #10

Hopefully with the LM4040. If not, might need to switch to arduino.

It is allllllllmost gone. There is some small jittering at some values. But I think after all my research, it's just the reality of the pico. I will try an arduino next. It is known to have a better ADC, and 5v versus 3.3v will hopefully mean slightly cleaner readings too.

Oh I'll also try a pot with higher resistance, as I've also heard that can improve things. My current pot is 5k, I will try a 20k one.

Switching from a Pico to an Arduino Nano solved all the noise issues. The Arduino's ADC is just better. It's unfortunate because Picos are much cheaper, but ah well.
