// Set to 1 if using DHCP, 0
// if using a static IP
#define USE_DHCP 1
// 0 -> Static IP, 1 -> DHCP

Now, look for the following two lines in the sketch and set them to the SSID and Passphrase that you configured your router to use in Step 2:

char szSSID = “DLClab”;
// the name of the network to
// connect to
char szPassPhrase =
“bogosity”;
// pass phrase to use with
// WPA2

Figure 8.

You can search the sketch using “***DLC” if you like. I put those comments into the code so that I could find them again later. You are now ready to compile and download your sketch.

To compile and download, press the box with an arrow pointing to the right in the upper left of the MPIDE window (refer again to Figure 8). After it finishes crunching data and downloading to your board, press the Serial Monitor button in the upper right of the MPIDE window. After about 40 seconds, you’ll see the serial port output shown in Figure 9. It typically takes about 40 seconds.

This all means that you now have a connection to your wireless network. Pat yourself on the back for your tireless efforts! If you look at your router, you’ll see your board listed in the DHCP client table which you will find by navigating to the “Status” tab and the “Router” sub-tab, and clicking on the “DHCP Client Table” button (Figure 10).

This router table is another place that you can confirm your connection status while troubleshooting your work.

Playing With Your New Toy

Now that you are running and on the network, let’s talk to the board! Figure 11 shows the web page that you will get when you use your favorite browser and type in the IP address given in Figures 9 and 10.
