  Operation "Pancho"


The purpose of this game is to remove as many body parts as possible in the least amount of time possible without touching the edges of the incisions. Once an edge is in contact with the tweezers or when the player removes all the pieces the game is over. An Arduino microprocessor was programmed to control a 7-segment display that shows the game’s timer. In order to determine when a player has touched an edge, each edge in the body is covered with a piece of conductive copper tape. The Arduino senses interruptions in the edges by detecting voltage changes. If an interruption occurs at the edges the Arduino is programmed to turn on an LED and create a sound on a buzzer. If the player presses the "start" button after signal he or she has removed all pieces, the timer will stop and it will display the time that took to remove all the pieces.
