Tic-tac-toe Game Based on Arduino and HMI

I think it's fun and not boring to get familiar with a new product by making games, and that's exactly why I did this project.
This project is to use Arduino UNO and Stone tft lcd display to develop a simple tic-tac-toe game.

Materials required for the experiment

Arduino UNO

Stone STWI070WT-01 tft lcd display

The system principle

Specify the first tap on the screen must be O, the second tap on the screen is X, has been doing this cycle. Set 8 arrays to store the number of O and X in each row, column and diagonal of each grid, as long as there are three of the same mark is the victory, then there will be a flashing red box to prove the victory of the row, column or diagonal, and then tap reset to start the game again.

Before I put the code, I really need to thank everyone on the forum for fixing my uploading error.
https://forum.arduino.cc/t/data-section-exceeds-available-space-in-board/873305
After solving that problem, my code was uploaded to the UNO board without any problems, which finally allowed me to implement my project. Thanks to everyone who helped me!

Hey dude, you really made a great project!

Very well done :white_check_mark:
I can't wait to see what other games you can put together.
