The Arduino Ethernet Shield is an additional circuit board that fits on top of a Arduino. It extends the Arduino’s capabilities with circuitry to connect to a network router, using a commonly-available RJ45 Ethernet cable. Your Arduino projects can communicate with the world through this connection – everything form fetching information from the internet and displaying it on a LCD screen, to providing publicly accessible, web-based tools that can control motors or other hardware.
Health & safety
- Ensure you are familiar with all H&S rules that apply to the environment you are working in.
- Identify where first aid can be found in your work space
- Keep all components dry and free from liquid spillages
- To avoid static, make sure your work surface is sufficiently earthed
First we changed the MAC address in the code to match the code on the back of the board.After having problems connecting from a university network, we set up the ethernet shield and plugged the ethernet cable into a home router. We loaded a basic client and was able to download an HTML page from the internet.
After a short break we set up a web server and was able to access it from a browser. We then were able to successfully ping the server from another computer using the network utility application on a Mac.
