Hi Folks,
This is my third Mach3 machine build but I need a slightly out of the ordinary solution.
I want to build a little 2 axis turning machine for wrapping wire on a mandrel at a varied pitch.
I would like to control the feed rate (via FRO%) using a foot pedal. I found a sewing machine pedal that is a simple potentiometer that uses a 3.5mm headphone jack (max 15V) that I want to use. I suppose could read the voltage via arduino if necessary but then what?
Can anyone suggest the best method for this? For instance is there a analog read capability built in to a basic BOB?
I want the pedal to go from 0% FRO with no foot and 250% pedal to the metal.
Any help greatly appreciated!!!!
