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.
