Introduction: Tic Tac Toe ( 3 in a Row )

Picture of Tic Tac Toe ( 3 in a Row )

This project is an electronic recreation of the classic Tic-Tac-Toe pencil & paper 2 player game. The heart of the circuit is Microchip´s PIC 16F627A microcontroller. I have included download link for a PC board PDF and also the HEX code for the chip burning. You will also find the assembly source code there. In a future Instructable, I will propose a"good looking"enclosure with large back-lit buttons.
