Just a quickie Arduino project that I ran across this morning: Sudoku on the Arduino. It’s pretty cute, since it uses the Arduino tvout library to generate video, meaning that you can display and play on your TV set. Neat! The only real description of the project is inside the zip file which you can find on the following Google Project host, but it’s pretty good at describing both the theory and implementation. I haven’t downloaded and tried it myself yet, but maybe this weekend.
