WiFi Pachube Client String

This example shows you how to answer a HTTP request using a WiFi shield. Specifically, it connects to pachube.com, a free datalogging site. The example requires that you set up a pachube.com account, as well as a pachube feed (for more information on setting up an input feed, please click here). Your WiFi shield will then connect to that feed and upload sensor data every 10 seconds.

Additionally, this example shows how to send sensor data as a string.

Hardware Required

Arduino WiFi Shield
Shield-compatible Arduino board
One analog sensor to attached to AnalogIn pin 0

Software Required

pachube.com account
pachube.com feed that accepts two data items

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.

WEP network passwords are hexadecimal strings known as keys. A WEP network can have 4 different keys; each key is assigned a "Key Index" value. For WEP encrypted networks, you need the SSID, the key, and key number.

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.
