Here is the article i spoke about. It is just a basic thing with some tests he done, but i thought might help( mind you , is with PIC uC's though).http://pk2lab.blogspot.co.uk/2011/11/controle-de-fader-behringer.htmlPS:Brazilian/portuguese but apart from the translator online, let me know if you need any help in case it plays up in the translation.
Where are you getting these faders anyway? And I second the question -- how much are they costing you? If they're built worth a crap, that looks like quite the feature set.
f you use the AD7147 chip to detect the touch, you don't have to periodically read in your Arduino loop.The chip can set an Arduino interrupt when anything is touched or released. (page 29)( www.analog.com/static/imported-files/data_sheets/AD7147.pdf )It handles 13 touch contacts so you would need 2 of them.
They are some faders from an old mixing console. My University proffessor got them few years ago and they are working allright.
And sorry for any grammatical or explaining mistakes.
