Description

An interactive memory game where players must remember and replicate increasingly complex sequences of lights on a 3x3 LED grid, using a keypad for input and a buzzer for audio feedback. The game gets harder with every step, and ends when the player makes a mistake.

Also, in my childhood I played a game like this, and I actually find it interesting to now be able to build one of the games I used to play when I was little.

Additionally, a web interface accessible via WiFi will display real-time scores, enabling players to track progress or compare results on the same network.

Motivation

I chose this project because I wanted to combine hardware interaction with Rust programming in a fun and visually engaging way. It’s also a good challenge for working with input devices, output displays, and real-time feedback.

Moreover, integrating a WiFi-connected web interface gives the project a modern touch, making it accessible and interactive beyond the physical device.

Architecture

• Game Engine (Rust) – manages LED sequence generation, user input validation, scoring, and game flow
• Input Module – receives keypad input
• Output Module – controls LEDs, buzzer sounds, and optional LCD display
• Random Generator – provides a new sequence every game
• Feedback System – audio (buzzer) + optional text (LCD)
• Web Server Module – serves a minimal website over WiFi where the current game score and history are displayed
• Game Controller – coordinates everything (input, output, logic, WiFi)

Log

Week 28 Apr - 4 May

During this week, I purchased all the necessary components for the project, including the Raspberry Pi Pico W, 4x4 keypad, LEDs, buzzer, jumper wires, and breadboards. I also finalized the game concept and documented the rules for how the Simon Says game will work. In addition, I designed an initial schematic for organizing the hardware components and planned how the modules (input, output, game logic) will interact. I also decided to build a WiFi-connected web interface to display players' scores.

Week 5 - 11 May

Week 12 - 18 May

Week 19 - 25 May

Hardware

A Raspberry Pi Pico W microcontroller is used to drive a grid of 9 LEDs arranged in a 3x3 matrix. A 4x4 membrane keypad allows user interaction, and a buzzer provides audio feedback. Two breadboards are used to separate control logic and visual interface for better layout and easier casing. WiFi functionality is used for connecting to a simple web server to display scores.
