Description
Pico-Wordle is a simple word guessing game inspired by the popular game Wordle. The game is designed to be played on a Pico device, and it is implemented in Rust. The objective of the game is to guess a secret word within a limited number of attempts. The brain is the Raspberry Pi Pico 2W, the word apear to 1602LCD with I2C Interface display, the feedback is given by MAX7219LED 8x8 Matrix Module and the input is given by the PC keyboard via wi-fi. Words history is displayed on a second 1602LCD up to 5 words.
Motivation
I like to play logics games, so I decided to create a simple game who can easly kill some time.
Arhitecture
Raspberry Pi Pico 2W

Log
- 21 - 27 april: Finish documentation
- 28 - 04 april - may: Finish hardware and update documentation
- 05 - 11 may: Start coding the game and functionality
- 12 - 18 may: Finish coding and add history of the words
Hardware
Using the Raspberry Pi Pico 2W, it will communicate with other components so when, someone give a input by keyboard(Wi-fi), the letter will be displayed on the LCD and after all 5 letters appear on the LCD, the player can press the Enter key to send the word. On the Matrix LED, the player will see the feedback of the word and the word will be visible on the second display.
