The embedded system is inspired from the original game Tic-Tac-Toe. The game has been around for centuries. The game is modified in a electronic sense, obviously, making use of Light emitting diodes and a keypad matrix. Now the LEDs represent the grid or spots that a player would place his/her symbol in, and the player is represented with a specific color in lieu of the X and O. In tic tac toe there are nine spots a user can choose to place his marker, and with this electronic version, the user has nine LEDs to choose from to key in his/her color. The game is interfaced via an Arduino Uno.
