Abstract :
Capacitive sensing is a way of sensing changes by measuring changes in capacitance. We decided to build a very simple mouse using home-grown capacitive sensors. Using an analog microcontroller (the Analog Devices ADuC841), a few simple chips, and a few cents worth of copper we put together a very simple capacitive-sensing based mouse. Along the way, we learned quite a bit ¿ including how a serial mouse really works.
