I followed the guide written by martijnthe.nl/2009/07/interfacing-an-optical-mouse-sensor-to-your-arduino/ and all was going well with it untill the update of my arduino programming environment which removed WProgram.h and now the library discussed in this demo no longer works. I have searched online and haven't found another working library yet and am looking for any help possible.
I'm working with the arduino uno and an ADNS-2610 sensor using arduino 1.0 programming environment and the Optimouse library from the guide linked above.
