Ok, I will do that soon tonight. I am fairly new to all of this so how would the 'G' pot vary by more than 15 if the pot is not even moving? I have a slide pot attached to a pedal so when the pedal is being pushed it pulls the slide pot. How would it vary by more than 15 if it is not being touched? I will check it out just on the input arduino and see if I get a 'G' value whichout touching it. If so, should I change the difference by greater than 15 to make it stop?
