What is Laser Tag?
Combat simulation game
Uses beams of light instead of bullets
Complete an objective such as capture the flag
Player-Sense
Ability for objectives to “see” players
Variable capture distance (modular)
Can be used with many different game modes
Communication
6 different microcontrollers
2 ESP32
2 ATmega 128
ATmega 168
Raspberry Pi 3
3 different communication protocols are used to interface all of the microcontrollers
SPI for intercommunication between microcontrollers
Wi-Fi using MQTT for long range communication
IR for perimeter checking
Future Plans 
Flag:
Introduce a speaker to announce when flags are capture/ contested.
Powered by rechargeable batteries to last a minimum of 1 hour.
Create a housing to place all flag circuitry and LEDS.
Use LEDs with a greater FOV to reduce power consumption and
Gun:
Create a laser tag gun with our current developed technology (IR send/receive, MQTT communication, and RGB LCD).
Powered by rechargeable batteries to last a minimum of 1hour.
Manipulate IR send/Receive data packets for different game modes and laser gun characteristics.
Problem Statement
Current Laser tag systems have no way of communicating crucial in-game information to players in real-time
Players must divert their attention from the battlefield to interact with a flag (objective).

Solution
Design a laser tag game that communicates and displays crucial in-game data to players in real-time
Create a realistic game mode where players do not have to physically interact with an objective
Allow users to play in a home setting compared to a pricey commercial setting
