Hi there, I am using a soft potentiometer to drive graphics in Processing.  It's running through a Diecimilla.  I need to figure out a way to get the soft pot to generate fixed values.  Whenever you remove the actuator (a finger in this case) from the surface of the pot the values default to a base value.  I need to devise a method to programmatically (in Processing) assign a constant value to the variable tied to the soft pot so it holds a value unless there is input.

I'm fairly certain this is a fairly generic piece of code if anyone can point me in the right direction I'd be grateful.

I would post the code I've attempted so far but it is not working at all and basically useless.

I know roughly that I need to be passing values into an array and comparing current values against recent values and if there is a drastic change then set the variable to last value before the change.  I also know modulus will factor in there somehow.  Being new to algorithmic thinking I can't quite figure out the logic. If someone knows of a piece of code out there that accomplishes this it'd be awesome.
