Conclusions
o Achievements
o Our system works
o Players cannot hear the tone emitted from the
Pallino
o This project will help reduce down time in the game
o Our project helps players determine which ball is
closest to the Pallino
o Improvements
o Make the system smaller
o Use low power electronics
