Building an Arduino-based laser game, Part 2: Firing the gun

Building an Arduino-based laser game, Part 2: Firing the gun: "This tutorial focuses on shaping the game. Now that you know the Arduino basics, you'll spend most of this tutorial building and testing a receiver for the 'Duino Tag gun. You'll get your hands dirty working with the code. We've got a bit of a chicken-and-egg problem: We can't actually test the receiver without having something to transmit, and we can't actually test transmission without having something to receive it. Fortunately, you'll learn a pretty easy solution for that."
