Temperature Monitor using Arduino Ethernet with Exosite.
  As IoT is getting popular, accessing the device over the Internet has become easier. There are many IoT platforms such as Xively, Thing Speak and XOBXOB. Exosite is an another IOT platform that allows connection with Arduino and explain how to monitor the temperature using Arduino and communicate with Exosite.
  Of course W5100 powered Ethernet Shield is used for the Ethernet connectivity and you can see the temperature graph as below.
  DIYmaker explain how to create Web Server with Arduino. In this tutorial they’re using the Arduino and Arduino Ethernet Shield and will control a LED through the Internet.
   The Arduino Ethernet Shield allows you to connect the Arduino to the Internet. It is based on the Wiznet W5100  chip with an internal buffer of 16k which is responsible for giving an IP address to Arduino. It has an RJ-45 ethernet connector 10/100Mb speeds. It also has a slot for micro-SD cards to store data to serve the network. For this, the library  is used  . To communicate with the Arduino, using the SPI port (pins 10, 11, 12 and 13) , and pin 4 if you work with a micro-SD card. These pins can not be used as digital inputs or outputs. It also has a button reset that resets both the W5100 and the Arduino board. Thanks to the Ethernet Shield we can use the Arduino as a web server or web client
Control the power with an Android and Arduino Ethernet.
  Controlling the outlets remotely with a smartphone or other device is a very useful. However it can be dangerous to work with mains current. Therefore one popular method is to use the inexpensive wireless power points that are controlled with inexpensive wireless data transmitters, and a great method of doing so has been documented by Stephen Arthur.
  In his project, an W5100 powered Arduino Ethernet board is used and connected to an inexpensive wireless data transmitter that matches the frequency of the receiver in the wireless power points. Then they can be controlled over the LAN with URL commands ? and to simplify this Stephen has written an Android app for his device to create a neat GUI, as shown in the following video:
