5.1. Project Overview

For this project, you'll be building a serial port infrared receiver using off-the-shelf parts you can pick up at your local electronics hobby shop. Don't worry if you don't fully understand how to read schematics—this will be as simple as pie. However, if you're still nervous or just not interested in building the hardware yourself, you can purchase a ready-made serial port IR receiver for under $20.

The difficulty in this project is primarily found in building the hardware. That's not to say that it will be difficult for everyone. If you have even rudimentary soldering skills, building the simple circuit board should not be any trouble. If you haven't done much soldering but you're willing to make mistakes (and possibly purchase the parts more than once), that skill can be acquired during this process. And hey, you can probably see from the pictures just how poor my soldering skills are, and I still managed to make it work.
