Connect an Arduino to Blender and use this bridge to move an object within Blender with a real world distance sensor. This tutorial will take you step-by--step through the process necessary to get simple communication working between Blender and an Arduino. Although the end result of this video is not in of itself too useful (albeit it is pretty cool) it is the foundation for an infinite number of projects that are possible once the bridge is created. One can use this method to create 3d scanners, motion capture suits, or physical control of virtual objects. This is the tutorial I wish I had had when I started down the path of creating my own motion capture suit.
