In this project, you will use Ethernet Shield and Arduino to create a simple Web server. Using the Ethernet library, your device will be able to answer a HTTP request with your Ethernet shield.
After opening a browser and navigating to your Ethernet shield’s IP address, your Arduino will respond with just enough HTML for a browser to display the input values from all six analog pins.
Any Analog Sensors
The Ethernet Shield allows you to connect a WIZnet Ethernet controller to the Arduino over the SPI bus. It uses pins 10,11,12 and 13 for the SPI communication.
Last Ethernet Shield model supports an SD Card slot on board. Digital pin4 is used to control the slave select pin on the SD card.
