Technology enthusiast Andrew Elwell has created a neat colour-changing lamp that's controlled over the internet using the MQTT internet-of-things machine protocol with an Ethernet-enabled Arduino-compatible board. The purpose of this is to change colour when certain details are found in a twitter feed, enabling remote control of the lamp. This could also become another style of notification device to monitor connected services - and is quickly demonstrated in the following video:
And as the Arduino is part of the system, all sorts of items can be controlled instead of simple LEDs. Either way, you can learn more and review the code links from Andrew's website. And for more, we're on facebook, Google+, and twitter - 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.
