Arduino lasertag, based on the instructable here: http://www.instructables.com/id/Duino-Tagger/ . The code on the page is outdated, so I rewrote it myself.
Currently it is very buggy and poorly structured, but functions at a basic tag game. My ultimate goal is to make a library that anyone with general programming knowledge and some cash can make a lasertag game out of.
If you would like to develop for this, there are 5 things you will need:
A good IDE, or at least a functional one. I use this one.
IRremote Library (I use version 1.0)
You will also have to replace the IRremoteInt.h with the one included in Custom IR.
If you need to test transmision and such:
At least 2 Arduinos (to send and recieve). Example
56khz IR receivers and Diodes (you can find them at mouser or digikey)
