Conclusions

University of Portland School of Engineering

o Achievementso Our system workso Players cannot hear the tone emitted from the

Pallinoo This project will help reduce down time in the gameo Our project helps players determine which ball is

closest to the Pallinoo Improvements

o Make the system smallero Use low power electronics
