XBox live enthusiast Andrew has created an amazing method of checking if friends are also logged into XBox live using an Ethernet-enabled Arduino hardware and some traffic lights. The Arduino checks via an API every five minutes to see if a particular person(s) is logged on and then shows the playability status using the traffic lights. What a great idea!
Another great example of how an Arduino can be used with something totally unexpected. To recreate this yourself check out Andrew's page. And for more, we're on 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.
