Last time I showed you a little play-around with Arduino and two servos.
Since my aim is to use it to control a webcam built on top of the two servos I have a program with a GUI that can do some image processing. I want to be able to control my “webcam-head” via the GUI so I need to send messages to the Arduino from my Qt (surprised?:D) application. I chose QextSerialPort because a friend of mine got nice experiences with it. I work with Ubuntu but it is also available on Windows systems.
