Introduction: 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.
Step 1: Quick Tour Video
Step 2: Device Views
Step 3: Circuit Diagram
Project is built around the PIC16F627A microcontroller from Microchip, an 18-pin microcontroller.
Step 4: Circuit Operation Details
Step 5: Basic Flowchart
Step 6: PC Board & HEX Code Download Link
Step 7: Components List
I recommend the use of an 18-pin DIL socket for the MCU.
Step 8: LEDs & Switches
Step 9: Breadboard Time
I used a wire to emulate the 9 switches.
Step 10: PART 2 Video
