Electronic Bag Toss Final Presentation

This project presents a fully automated bag toss scoring system developed by Tim Williams and Richard Deward, advised by Professors Miller and Nattu during the Winter 2012 Senior Design course. The system is designed to accurately score bag toss games using a combination of microcontrollers, image processing algorithms, and RFID technology. Key components include a user interface for scoring display, sound effects, and team identification. This innovation enhances gameplay by providing real-time scoring and automatic adjustments for missed shots and bag placements.
