Convert optical mouse into Arduino web cam

Franci has written this tutorial describing the process used to convert a mouse into an Arduino web cam. In addition to the Arduino, all you need are an Ethernet shield, an optical mouse with ADNS-5020 sensor and a 10K ohm resistor. “An optical mouse uses a small camera that records the surface to calculate movements of the mouse. In this tutorial I will show you how to display the video signal of this camera in your browser. The mouse I took apart was an old Logitech RX 250 which contains ADNS-5020 optical sensor. This sensor records 15×15 pixel images in grayscale. It also calculates X-Y movements of the mouse.”
