Super simple and Cheap Android Touch Interface Part 1

As some of you might know there is a build in web server in V-Control that lets one create graphical user interfaces for V-Control. But to do this, HTML and JavaScript knowledge is necessary. In this article, I will describe a simple solution using an Android device, a cheap Bluetooth serial port and a V-IO interface. The V-IO is not really necessary, a simple Arduino Uno is sufficient, but with V-IO we also have a housing for the Arduino. Read more

As far as a status change of a device occurs, the information is sent to the web application. All we need is to write a handler for this status message and show the new status in our GUI.
