You wrote: "do you mean to use analogueRead() and read a PWM value [...]". No, I mean what I wrote, nothing more.

@EdgarBonet Srry, it should be .1uf. So do you mean to use analogueRead() and read a PWM value insted of a real analogue voltage between 0v and 5v.

Thanks for this, but I believe the answer that states that I was incorrectly assuming that the A'N' pins were analogWrite() capable is correct. I definitely know I had current flow without need of a resistor, capacitor or other intermediaries. I made bold mis-assumptions as to what pins can do what.
