Abstract
Cornhole is a very popular game that leads to hours of fun and family
bonding; however, the scoring system of the game leads to much
controversy. Currently the scoring system of the game is performed
through all manual calculations which can be performed incorrectly. The
goal of this project is to design an electronic cornhole scoring system by
implementing various hardware and software platforms developed from
research.
• 
Cornhole scoring calculated and maintained electronically.

To determine when a bag falls into the cornhole
as opposed to off the board there must be a
specific detectable event that happens.
All cornhole bag data at the end of the round must
be known to calculate the appropriate score
Score needs to be displayed to users
To enable wireless operation portable power must
be used. Also cornhole is usually outdoors away
Must be powered by small portable voltage sources from AC power.
Total equipment must fit into average size truck bed, To enable people who want to play anywhere, it
75" x 61" x 21", for transportation

Cornhole bags are thrown and have high impact
so components must be protected from being
broken. Also moisture from playing outside can
damage the components
The game will be played at various locations
The average person must be able to play with
minimal thought and reference to instruction
manual
Must decide which events require what type of audio To enhance user experience, and most players
output if necessary, and play audio, audible up to 50' will be about 30' apart from one another.

Hardware
To create an electronic cornhole game, two separate sensing systems
will be implemented to automatically detect and determine the score.
Each bag will contain an accelerometer and a radio frequency
transmitter (RF) that will send a signal to a receiver connected to the
microprocessor. The signal will be used to determine the location and
movement of the bag. The board will be equipped with force sensing
resistors (FSR) that will indicate weight changes on the surface caused
by the bags landing on the board. When combined the two independent
systems will allow the microprocessor to determine the appropriate
score and output a signal to the scoreboard as well as play audio
corresponding to the game's events.
System must compile all cornhole bag data at the
end of the round and update score
Must send signal to seven segment displays and
display score, visible up to 30' from the scoreboard
Components inside cornhole bag must be protected
from impacts up to 120 lbs, and light moisture
Scoreboard and main circuits must be able to
withstand transportation

Software
The focus of the software design is based upon the location of the bags.
The score will vary based upon if the bag is on the board, in the
cornhole, or on the ground. Several algorithms will be utilized in the
microprocessor to determine the location of the bags. The data from the
weight sensors will be essential in the calculation of the score. Once the
data from the sensors is received and analyzed, the microprocessor will
output a signal to the scoreboard and speakers to display the correct
score and play the corresponding audio.
