This example shows you how to answer a HTTP request using an Ethernet shield. Specifically, it connects to [[(http://www.)cosm.com]], a free datalogging site. The example requires that you set up a cosm.com account, as well as a cosm feed (for more information on setting up an input feed, please [[http://community.cosm.com/using_the_website#inputs | click here]]). Your Ethernet shield will then connect to that feed and upload sensor data every 10 seconds.

!!!Cosm Client
This example shows you how to answer a HTTP request using an Ethernet shield. Specifically, it connects to [[(http://www.)cosm.com]], a free datalogging site. The example requires that you set up a cosm.com account, as well as a cosm feed (for more information on setting up an input feed, please [[http://community.cosm.com/using_the_website#inputs | click here]]). Your Ethernet shield will then connect to that feed and upload sensor data every 10 seconds.

(:div class=BOM :)
!!!Hardware Required
* Arduino Ethernet Shield or Arduino Ethernet
* Shield-compatible Arduino board
* One analog sensor to attached to the Ethernet Shield

'''Software Required'''

*[[(http://www.)cosm.com account]]
* [[http://community.cosm.com/using_the_website#inputs | cosm.com feed ]] that accepts two data items
(:divend:)

!!!Circuit
(:div class=circuit :)

The Ethernet shield allows you to connect a WizNet Ethernet controller to the Arduino via the SPI bus. It uses pins 10, 11, 12, and 13 for the SPI connection to the WizNet. Later models of the Ethernet shield also have an SD Card on board. Digital pin 4 is used to control the slave select pin on the SD card.

The shield should be connected to a network with an ethernet cable. You will need to change the network settings in the program to correspond to your network.
