Add an Ethernet shield to your project to connect your Arduino or Iskra to the wired network. An Ethernet shield will let your device act as a full-fledged network device with the ability to communicate with similar devices, conventional computers, printers, Internet services, your favorite electronics website, and other network resources.

Use this Ethernet shield to create your own Internet of Things project. You could:

  • Control devices through the Internet
  • Display online services such as Google or Wunderground
  • Run a small web server

The board is based on the Wiznet W5500 chip, which supports TCP and UDP protocols. Up to eight connections can simultaneously be in the open state. Work is supported by the http and https protocols.

Connection and Programming

To connect to a local network, use the standard 8P8C (RJ45) connector on the board. Use one end of a patch cord to connect to the router or modem, the second to the Ethernet shield.

The pinout is compliant with Rev3. For communication with the control board use the SPI protocol. The Ethernet shield uses the MOSI, MISO, and SCK pins, and also the 10th as CS for the W5500 chip.

Alternatives

It's hard to implement XML processing, JSON, to distribute pages with dynamic content on a microcontroller. The limited resources make it painfully difficult. Therefore, if you need a project with a powerful web server or client, take a look at single-board computers like Raspberry Pi
