Bomb Deactivation Game

  
`Should I cut the blue wire... or the red...?` This is a very common phrase in many movies when the action hero has a bomb in front of him with little time left and he has to choose which wire to cut and stop the bomb from exploding saving millions of people. This game is just that... a count down timer and 4 wires of different colors. The player has to remove each wire until it deactivates the bomb.

All the wires and components create a better game experience. Anyway I have made a pcb drawing making it possible to create a clean build. The PCB used for this Project is double layer and its size is 70.79 mm x 42.01 mm. Turning the power on, the display and piezo will start small introduction. After the introduction, the message "S1" will appear on the display meaning that S1 needs to be pressed for the game to start. All four wires must be plugged in. If one of the wires is not plugged in, the message "EE" will display meaning that an error occurred and...
