I might be blind, stupid or barking up the wrong tree, but I can't find any information in here regarding how a pot's value affects the function of the ADCs. I know that PICs have a prescaler to customize linearity and such, but I'm having a hard time getting the ADC on a PICAXE to work exactly...

Can anybody tell me what effect the PWM frequency has on a given application? I've tried using various frequencies to control a small DC motor, but I can't really definitively determine what exactly happens when I use say, 10kHz vs. 15kHz vs. 20kHz or whatever. This is quite curious to me...
