And now for something different and very usable comes the ATSIC from Instructables user "hackitbuildit". This is a touch-screen controller for Apple's iTunes software and gives the creator the ability to create a wide variety of interface options for music control. It may sound complex but is in fact rather simple. The touch screen is a simple four-wire resistive model available from many sources, which is connected to the Arduino's analogue inputs. The system also has an LCD display model for playback information.
The only catch is that the system relies on the Arduino being connected to an Apple Macintosh computer, as the commands from the touch-screen via the Arduino are interpreted in Applescript. Nevertheless it's a greta project and demonstrated further in the following video:
If you're an experienced Arduino user and interested in more advanced Arduino projects - get yourself a copy of "Practical Arduino" by Jonathan Oxer and Hugh Blemings:
