A Tic-Tac-Toe machine! Two players play on one 9 button pad, and win conditions are automatically detected.
If you want to watch me build the machine step-by-step, here's a video! Frames are spaced at 3 second intervals.
Log in as singleplayer. You'll be standing in front of the control panel. As the signs say, the left lone button resets everything, the center panel with 9 buttons is the entry pad, and the lights to the right flash the color of the winning player. Of course, the top screen shows the game progress. In the indicators, Green represents X, and Red represents O.
Make sure you wait a bit after pressing a button before pressing another one. Those buttons won't be rushed, and get cranky if you try to hurry them.
Here's a sample session:
- Press Reset to reset the game if it is not already reset.
- The green light on top of the entry pad is glowing. That means it's Green's (X) turn.
- The Green player presses the desired button.
- The green light turns off and the red light illuminates. That means it's Red's (O) turn.
- The Red player presses the desired button.
- The red light turns off and the green light illuminates.
- This cycle repeats until a player wins or the board is filled.
- If a player wins, the player's color will flash on the right indicator panel.
- For the convenience of other users, reset the machine so they don't have to.
