Inspiration
It can be difficult for winded players to keep track of a game's score in the hot Miami heat. Some teams may go without scoring after 5-20 minutes for whatever reason which can cause players to lose track of score. An app on a smart phone may provide a scorekeeping solution, but these devices are too bulky and can affect a player's performance if they have them in their pocket; plus, smart phones can be easily damaged. This project supplies a simple and light solution.
What it does
A small RF transmitter sends a signal to a RF receiver connected to a microcontroller that updates a team's score on a display. Every time the score is updated, a human-like voice announces the score for the team that gained a point. If an error was committed, the score can be decremented.
How we built it
We gathered parts we had lying around and make the best of it. Equipment used: Arduino, LCD display, RF receiver, RF transmitter, and a text-to-speech module.
Challenges we ran into
- Insufficient power supplying to each component
- Lack of default digital input/output pins
- Preventing random characters from appearing on the display
- Refreshing the display correctly after sending RF signals
Accomplishments that we're proud of
Rapidly created a simple, useful project.
What we learned
Execution time of instructions on a microcontroller is crucial.
What's next for Wireless Embedded Scorekeeper
- Creating an amplifier for louder score announcements
- Battery supply rather than computer power provided via USB
- Larger and higher resolution display to improve accessibility and add more visual features
- WiFi functionality allowing players to communicate with the device
