I call this "LED Pong". I built it from scratch and I based the design on a 1-meter strip of individually addressable LEDs and an Arduino Uno. Pong was one of the first video arcade games ever made. It was released by Atari in 1972 and if you are unfamiliar with it, this video provides a good overview of the gameplay: http://www.youtube.com/watch?v=pDrRnJOCKZc
Following my design is not for the faint of heart, unless you plan to have printed circuit boards manufactured, you will need to have excellent solder skills. You will also need a lot of time, patience, and some money. This project took me about 6 months to complete (Don't worry, you can probably finish it in a couple weeks if you're motivated) and I spent about $60 on parts. However, you can modify the project to suit you needs (and save money). If you don't want all the bells and whistles, you can just omit them! In fact, this project really only needs an Arduino, two buttons, and the LED strip to work! Everything else is just extra.
I have divided this Instructable into two parts: The first part covers the building aspect and the second is an in-depth look at the software side of the project. I will do most of the in-depth explaining (I.E. How shift registers work) in Part 2. Also, I taught myself how to do most of the programming so my way may not be the best way to do something. If you know of a better way to code a function, please let me know in the comments section!
It is a good idea to test the components (LCD, LED strip, etc.) before and after you install them. To do this you will need to install the necessary libraries and then load the example from the correct library. I provide links to the libraries and tell you how to install them in step 9: "Part 2: Software".
As a last note, if you are having problems, check out step 19: "Troubleshooting, Troubleshooting, and more Troubleshooting" for some ideas on how to fix any problems. Also, be sure to frequent step 20: "Updates" for any updates/upgrades I do in the future.
