The hardware is easy and the code isn’t hard, so let’s start!! We are going to use an Arduino, draw (!!) our own interface on a piece of paper, and than we are going to use it to control a simple slide show inside vvvv.
In this, rather long tutorial, I will be showing you how to receive Arduino messages inside vvvv, and use those to make a basic picture rotator.
We will create a capacitive sensor for Arduino, using a pencil and a piece of paper. Once that is done we will modify the Arduino code so we can use the Serial communication (RS232) inside vvvv to receive the messages and convert them to a simple interface to control a basic picture rotating slide show.
On the vvvv website, under the video tutorials, you can download a package that contains all the patches, code and circuits you will need to reproduce this project.
