Laser Tag

A digital logic implementation of the traditional laser tag game, created spring 2012. The project contains two modules, electronics that represent a laser gun, and electronics that represent a vest. The gun is programed to any one of eight potential players (equally split into two teams) using a DIP-switch. The three bit binary number is compiled into a string with additional information, which prompts the vest to identify the incoming player ID when shot. When triggered, a shift register sends the string through a laser using rapid on-off pulses. A phototransistor on the vest registers the laser pulse. A combination of shift registers, multiplexers, and logic gates decode the transmission and increment a counter for the team that was just hit. Similar to the laser gun, the vest has a player ID input and ignores friendly fire. 7-segment displays show the number of times each team has been hit.
