Hello Community 
my current approach is to build a Motorfader Controller:
Arduino Uno with Motor Shield gets (for testing purpose fix programmed) values from elsewhere.
it Should drive the Motorfader to the exact level.
so it has to continuously read the current position (analog value) from the fader track.
do someone know about an similar project or some resources to get some starting point / ideas from?
till know i found things like:
MIDIbox Hardware Platform, Motorfader NG Module
and
DIY Servo ( this one is for very slow positioning for time-laps photos)
I hope there are some Ideas around
sunny greetings
Stefan
