Measure Movement on your Arduino with a Mouse - How to connect a standard mouse to an Arduino.
A mouse is a multi axis movement sensor that can be used for so much more than an on screen pointer. It's incredibly cheap and very accurate. Connect one to your project and you're instantly able to measure your robot's travel, speed, etc. without having to resort to expensive incremental encoders.
I'll show you how to interface with a standard wired mouse, give you free access to my PS/2 mouse library code to drive it and then use it to prototype my spinner control for an arcade game controller project (one for the near future!).
