Connect With WPA

This example shows you how to connect to a WPA2 Personal encrypted 802.11b/g network with the Arduino WiFi shield. Your Arduino's serial monitor will provide information about the connection once it has connected.

(:div class=BOM :)

Hardware Required

• Arduino WiFi Shield
• Shield-compatible Arduino board

(:divend:)

Circuit

(:div class=circuit :)

The WiFi shield uses pins 10, 11, 12, and 13 for the SPI connection to the HDG104 module. Digital pin 4 is used to control the slave select pin on the SD card.

You should have access to a 802.11b/g wireless network that connects to the internet for this example. You will need to change the network settings in the sketch to correspond to your particular networks SSID.

For networks using WPA/WPA2 Personal encryption, you need the SSID and password. The shield will not connect to networks using WPA2 Enterprise encryption.

image developed using Fritzing. For more circuit examples, see the Fritzing project page

In the above image, the Arduino would be stacked below the WiFi shield.
