There aren't too many methods for uncomplicated remote-control of an Arduino over the Internet, (for example Teleduino) - and that's why we're happy to show you the new "Commanduino" system devised by Fabrizio Caldarelli. It's a simple system that uses customised URLs to activate digital pins, and as it's still a work-in-progress more features will be added soon - or you can work on it yourself.
The Commanduino system works with either a TCP or UDP protocol, and could easily be integrated with a graphical HTML front-end hosted on an end-user's web device. To learn more and examine the code, visit the Commanduino github page. And for more, we're on facebook, twitter and Google+, so follow us for news and product updates as well.
When putting together your next Internet-enabled Arduino project - save time, space and money with the Freetronics EtherTen. Apart from being fully Arduino Uno-compatible, it has onboard Ethernet, microSD socket, full USB interface (so you don't need a costly FTDI cable just to upload a sketch!) and supports optional Power-over-Ethernet.
