Um, I did a google search and couldn't see anything on turning a resistive load (which is what I am guessing a variable resistor is) to a capacitive load. Could you offer any advice here?
 
I found an article that talk about using Pots on the Mega8 and they look like they are pretty raw?
 
Thanks for the heads up!
