Caruntu Vlad-Andrei 1222A This project is meant to recreate the all-famous game known as Tetris. It does this by displaying the game in an distinct and charming way, through LED lightups which the blocks and their falling across a 32×8 Matrix of LEDs. In case you don't know what the game consists of, here is a short description of it: Tetris is a puzzle game in which geometric shapes called “tetrominoes” fall down onto a playing field, and the player has to arrange them to form gapless lines. This particular variant of the game allows for a competitive multiplayer game to take place, by having 2 players stack blocks until one of them reaches the top and thus gets a game over.

The following is a diagram representing the overall idea for the project:
