If your team is using the open-source "Jenkins" continuous integration server, a lot of fun can be had by creating an unusually-large status display. In this example, the folks from Helpshift have used an Ethernet-connected Arduino to receive status from the server via python. Once received, the Arduino controls the large LED-based traffic lights via darlington transistors to get the message across very clearly, for example:
Recreating this project can be as easy or otherwise as required, for example you can just use smalled RGBLEDs instead of making your own traffic lights. But where's the fun in that? Either way, check out the project page for code and inspiration. 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.
