Description
The project consists of an implementation of the famous game 2048. The goal of the game is to reach the value 2048 by combining powers of 2 on a 4x4 board (classic mode). The player combines numbered tiles by moving up, down, left and right, using physical buttons. The game runs on a Raspberry Pi Pico 2 and is displayed on a color LCD.
-
The system utilizes five buttons for the gameplay: up, down, left, right and reset.
-
The LCD screen showcases the grid and the numbered tiles.
-
A buzzer that makes a sound when a milestone is reached.
Motivation
As a kid, I loved playing simple, clever games like 2048, fascinated by how such a basic concept could be so addictive and satisfying. That experience stuck with me and inspired this project: building my own version of 2048 from scratch.
While planning the system — from managing inputs to handling graphics and game logic — I realized it’s more than just code. It’s also about creating a smooth, engaging experience, which taps into my love for design and user interaction.
Architecture
The Raspberry Pi Pico 2W serves as the central control unit, directing and managing all other components utilized within the project.
The LCD serves as an interface for showcasing the grid and numbered tiles, it is connected to the Pico through SPI
The buttons act as the primary input method, they are connected directly to the Pico's GPIO pins
The buzzer emits sound cues for actions and is connected to a GPIO pin

Hardware
- Raspberry Pi Pico 2W:
- Purpose: Controls all components.
- Function: Acts as the main controller, coordinating the operations of buttons, buzzer, and the LCD display.
- LCD Display:
- Purpose: Displays the grid and numbered tiles of the 2048 game.
- Function: Provides a visual interface for the user, updating the display dynamically as the user moves the tiles and merges them.
- Buttons:
- Purpose: Serve as the user input method for controlling the game.
- Function: Allow the player to move tiles in four directions (Up, Down, Left, Right) and reset the game.
- Buzzer:
- Purpose: Provide auditory feedback during gameplay.
- Function: Emits sound cues for actions such as tile merges, successful moves, or game over.
