Set up an array of IR LED and detector pairs so that the pendulum only
breaks one of the beams. Run the signals from each detector into a
decimal to BCD converter and read this value directly into the computer.

Personaly, I like the joystick idea best since it would provide both
pitch and roll measurement but the IR LED approach gets rid of the
A/D converter.

HOWEVER: if you used an A/D converter with an 8 to 1 input mux you
could measure pitch, roll, battery voltage, radio link signal strength,
drive motor temperature, and three other analog parameters with the
one chip.
