ABSTRACT
This report will describe the design and implementation of the project. The Senior Design
Project is the Computer-Based Measurement Device for a Soccer Free Kick. This device is being
designed and constructed to fulfill the B.S. Electrical Engineering Technology Degree
Requirement.
The device was invented to introduce officiating technology into the sport of soccer. The
device will allow the referee to quickly determine if the defenders are 10 yards away from the
ball like they are required to be by the rules of the sport. Not only will the device allow the
referee to make this decision accurately, it will also speed up the time of inactivity during a free
kick. Never again will a referee have to pace off 10 yards or even judge the distance with his
line of sight. With the Computer-Based Measurement Device for a Soccer Free Kick, the referee
will be able to do make these improvements to the game and will also have data to rely on
when a player or coach complains about the defenders being too close to the ball during the
free kick.
The idea of this device originated from the love of the sport of soccer and the desire to
introduce technology, another of the passions, to the game. During the past year of working on
this project, there was a lot lessons learned, not only about the technology of the device, but
about project management, and documentation programs that the group had never used
before.
Keywords: Arduino Uno, Arduino Software, Ultrasonic sensor, LCD screen, push button, digital
