Amongst the multitude of things you can do with MATLAB software is the ability to remotely control an Arduino board via Ethernet. With the included code you can create a visual interface to simply control Arduino digital outputs, and expand on them with your own requirements. Although the project uses a separate Arduino Ethernet shield you could also use an integrated board such as an EtherTen.
An interesting and useful example for MATLAB users out there - click here to get started. And for more, we're on twitter and Google+, so follow us for news and product updates as well.
If you're looking for an Ethernet-enabled Arduino-compatible board, consider one of Ethernet-enabled boards, such as the Freetronics EtherTen - the Arduino Uno-compatible with onboard Ethernet, microSD socket and optional PoE:
... or for more program space, I/O ports consider the Freetronics EtherMega - the Arduino Mega2560-compatible with onboard Ethernet, microSD socket and optional PoE:
