Arduino Tic Tac Toe

This weekend I spend some time building a simple game of tic tac toe using an Arduino and a variety of simple components, both analog and digital. Here is a video that takes you through the process of creating this game. You can download the code here. I have left all comments in the code so that you understand how it is built. I am sure there are many ways that this code can be improved and/or streamlined.

    Pete, sorry it took me so long to get back to you on this. Can you tell me about what specific version of Arduino and the IDE you are using? That may help me figure out what is going on.

    Pete, I’ve removed the old code from this post because I noticed how the formatting was getting all messed up. I’ve added a link where you can download a properly formatted version of the code. Let me know if it works now, in case you decide to try it.
