Now that you've completed the wheel, its time to install it. Place it in the cage and connect the connector to a free serial port on your computer. I used a serial port extension cable since the cable I made was too short to reach my computer on the floor.
If your computer is too new to have a serial port you can buy one for cheap on Amazon or at your local electronics store. If you're running some variety of Linux or Mac I would recommend this one from Keyspan
that will work well.
