Now that you have an idea of how to connect a GPS device through the I/O pins on Arduino, let's look at a different way to provide GPS information to Arduino, through a GPS shield. There are several shields available, including one from Dexter Industries that is available at many online retailers, such as www.amazon.com.

To connect to Arduino, simply push the shield on your Arduino device so that it looks like the following image:

You can use the pin labels to match the pins on Arduino. Now, it is securely on top of your Arduino device; let's look at how to access the device via the SW.
