TicTacToe

thingiverse

We created a Tic-Tac-Toe game using RWTH Aachen-Fablab's resources as a warm-up exercise. The rules are standard - three in a row horizontally, vertically or diagonally wins. However, our version is played with stereo jackets featuring red and green LEDs. Each player has a common contact and two differentiating contacts. The game board's female connectors are connected to an Arduino, with each color having its own input pin. The computer player uses another 6 pins for its LED matrix, wired in rows and columns. A reset button starts the game. For a physical component, we designed a box using a laser cutter on a piece of wood. The electric circuit can also be etched or milled. We created a template for four sides that can be glued to the game board. However, the wiring was more challenging than expected and caused some issues. A bigger box would have made wiring more comfortable, and using thinner wood could have alleviated some problems. The final design features an engraved wooden box with a plugged cap and base for easy access to the Arduino, battery, and wiring repairs. The game looks great, but the focus is on the making process rather than the game itself. An alternative design could include a plexiglass front with a 3D-printed box or even a paper box created with scissors and a printer.
