Scoreboard

An easy way to keep track of your score.

I've played too many games of table tennis where the score was forgotten. I wanted an easy solution to prevent that from happening, so I developed this Arduino-based open source scoreboard.

Keeping track of the score is as simple as pushing a button.

Even though this scoreboard is programmed specifically for table tennis, it could be re-programmed to score the sport of your choice. All it takes is a little code-tweaking on your part. It might even make a decent clock or count-down timer. It's all possible since it's open-source.
