Wordle
A Rust-based embedded implementation of the popular word-guessing game.

Description
The project replicates the popular Wordle game developed by the New York Times, implemented using Rust on embedded hardware. Players must guess a secret 5-letter English word in 6 tries, receiving feedback on each guess through color-coded hints:
Green: Correct letter in the correct position
Yellow: Correct letter in the wrong position
Gray: Letter not in the word
Motivation
This project is a nice first dip into the world of embedded systems. Wordle is a simple but engaging game, making it a great candidate to explore user interaction on low-power hardware while familirizing myself with Rust in an embedded environment.
Architecture
The core components of the project architecture include:
Game Engine (Rust): Handles word selection, guess evaluation, and game logic.
Input Handler: Receives user input from a connected keypad.
Display Driver: Outputs the game state on an LCD using color indicators. Architecture Overview:
[Keypad/Touch Input] ---> [Input Handler] | v [Game Logic Engine] | v [Display (ILI9341)]

Hardware
The project is built on a Raspberry Pi Pico platform with peripheral components for input, output, and storage. The display provides visual feedback while the keypad serves as the main input method.
