Edit: I've added the ability to restart the game with a different speed or the same speed after the game has been finished. You can view the flow chart of how the game is played below under the Gameplay heading.
All digital files that are available, including the schematic, board files, code, and gerbers are located on my GitHub.

I bought a Printrbot from Kickstarter because I've been interested in 3D printing and thought this was the best and lowest-cost way of doing it myself. When I finally recieve it, I will design a case for this game. I will add the files when I finally make it.
I have also thought about making another version of this game with nothing but surface mount parts. I plan on adding two colors of LEDs so it can randomly pick a position to stop the LED by lighting that position in a different color. It would also have the logic to determine if you've won by matching them or lost by being off. This is currently nothing but an idea but I will but I will put work into it when I have more free time after school is out over the Summer.
