Enabling the Wi-Fi shield in the Arduino
IDE
Now that the shield is attached, you can access the standard library examples for Wi-Fi.
Navigate to

WiFi
and you'll see a number of useful example programs, as
shown in the following screenshot:
These are all very useful examples. Just to make sure that your shield works, you can select
ScanNetworks
. Run this program and open
Serial Monitor
. This program scans for avail-
able networks and should show a set of networks that are possible to connect to.
However, if you want to configure your Arduino as a Wi-Fi web server, you can access it
via the Internet and get or send information to your Arduino via the Wi-Fi network. An ex-
cellent example to get you started is
SimpleWebServerWiFi
. Here, you enter your SSID
and password and you can turn on an LED. I would suggest that you change the LED to pin
13, and you can then turn on and off the on-board LED via the instructions at the top of the
file.
