Table Tennis Score Keeper

Description

This project allows users to keep track of table tennis points and who serve it is while playing. Each side has the ability to increase or decrease their points. They yellow button resets the score back to all zeros. The black button changes who started serve which is indicated by the players score blinking. The last button toggles the game mode between 11 points or 21 points to win. It also keeps track of serve if the points get to deuce. The remotes communicate to the score board using bluetooth. The remotes are in deep sleep, consuming a few microamps of current. When someone hits a button it comes out of deep sleep and starts broadcasting the the action through ble ssid that the score board will see and take appropriate action.
