Most people know how to blink a few LED’s using an Arduino. With this cool project you can take this knowledge a step further and build your own Arduino powered laser tag system. This awesome project uses an IR transmitter, a piezo, IR receivers and a number of LED’s for visual effects. As you would expect, the IR transmitter is used to shoot your opponents and the IR receivers are used to determine if you have been shot!
This is a really fantastic project if you are looking to expand your Arduino skills. The project is well documented and includes full code examples! To get started on this awesome project check out the instructable by j44.
