Arduino Nano-based bicycle laser tag game

This Arduino Nano-based laser tag game was built to be played on bicycles. Each laser tag target is attached to a safety vest. The goal of the game as coded is to hit an opponent's target 6 times with a handheld laser pointer to get them out of the game.  Each successful hit makes the team lights (blue or green) turn off and turns on the red lights along with playing a sound. The sixth successful hit makes the team lights turn off and the red lights blink three times, and an elimination melody plays.

This game was designed to be played 6 vs 6 on bicycles in a designated area of a parking lot during the 2016 Atlanta Cycling Festival opening party.
