There's an almost infinite number of uses for the "Internet of Things" - some useful, some perhaps not. However the following project by Instructables member tamberg shows how you can harness the IoT for your own means throught the description of a neat gauge project.
As you can see from the image below, a simple gauge has been made to display the location of a particular person - which is driven via an Ethernet-enabled Arduino or compatible. This is controlled via a REST API running on the Arduino, which listen for commands from the ITTT (If This, Then That) cloud-based service. By tweakinhg ITTT that to your needs, you can control a neat web- or Android device-based control panel to control the gauge from almost anywhere.
An excellent example of how easy it is to harness the IoT with Arduino - so head over to the Instructable page to get started. 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.
