Couple of general questions-- I want to use the arduino as a sort of “digital potentiometer”, controlling the resistance to a couple of oscillator circuits. In this way I can control pitch and amplitude of the oscillators from a data set. I have an arduino Uno, and I know that it doesn’t have any analogue outputs, just PWM, but perhaps this is ok? or maybe there is an indirect way to go about this? either by converting the PWM or ? Sorry, I cant be more specific at this moment.
On a completely seperate idea— I would like to write a program that tunes a (guitar) string. My big wonder is if there is a library that will allow me to track frequency/pitch of the string? Or would this be something I would have to use Max/maxuino for? I’m trying to keep it as simple as possible so doing this without some external software would be great!
