- The Ethernet Shield for arduino enables you to connect your development board compatible with Arduino to the internet and start building IoT projects in mere minutes.
- Just plug this module onto your board compatible with arduino, connect it to your network with an RJ45 cable (not included) and follow a few simple instructions to start controlling your world through the internet.
- As always with Arduino, every element of the platform – hardware, software, and documentation – is freely available and open-source.
- This means you can learn exactly how it's made and use its design as the starting point for your own circuits.
Ethernet Shield for Arduino
To use the shield, mount it on top of an Arduino board (e.g. the Uno). To upload sketches to the board, connect it to your computer with a USB cable as you normally would. Once the sketch has been uploaded, you can disconnect the board from your computer and power it with an external power supply.
Connect the shield to your computer or a network hub or router using a standard ethernet cable (CAT5 or CAT6 withRJ45 connectors). Connecting to a computer may require the use of a cross-over cable (although many computers, including all recent macscan do the cross-over internally).
The shield must be assigned a MAC address and a fixed IP address using the Ethernet.begin() function. A MAC address is a globally unique identifier for a particular device. Current Ethernet shields come with a sticker indicating the MAC address you should use with them. For older shields without a dedicated MAC address, inventing a random one should work, but don't use the same one for multiple boards. Valid IP addresses depend on the configuration of your network. It is possible to use DHCP to dynamically assign an IP to the shield. Optionally, you can also specify a network gateway and subnet.
The latest revision of the Ethernet Shield includes a micro-SD card slot, which can be interfaced with using the SD library.
