Laser Duel is a project made by XiaoXing Zhao, Fred Kummer and Douglas Katz for their ECE 4760 Final Project. The two guns use Nordic nRF24L01 radio transceivers to talk back to a base station which monitors the game play and keeps score. Each gun has some visual indications so the players can see what the health is and there is also a speaker for some audible indications for things such game over.
“Each gun has an infrared emitter for shooting and an infrared detector that detects if the player using the gun was shot. We designed the shooting mechanism such that when the player presses a trigger on the gun a 38 kHz infrared wave will be emitted. If such IR radiation is detected by another gun, then the shot registers as a hit and the player being hit will lose one point of health. Each player starts off with 8 health and the game will end once a player reaches 0 lives, or if someone operating the basestation signals to end the game early. We equipped the guns with a ultra low power radio that sends vital statistics about the player such as player health and player identification to the base station.”
