One of the great benefits that comes with the Raspberry Pi is the ease of connecting external hardware to the Internet thanks to the onboard network interface. This synergy can be harnessed for your benefit and one neat example of this is the connected light device described by Kevin Gleason.
His example of a connected device is the ability to control a RGB LED connected to the Pi from an Android device via the PubNub cloud-based data service. This is made easier thanks to PubNub's python and C++ libraries for Raspberry Pi - along with notes on creating an Android app for control.
Even if you're not interesting in controlling lights, this project is an excellent framework for creating connected devices you can control from afar - so visit the project's Instructable page to get started. And for more, we're on facebook, Google+, and twitter - so follow us for news and product updates as well.
If you're looking for a neat way to add external circuitry to your Raspberry Pi model A+, B+ or 2 model B then check out our new PiBreak Plus Raspberry Pi Prototyping Board:
This is a great way to add your own electronic components, circuitry, sensors or other devices to your Raspberry Pi model A+, B+ or 2 Model B - any of the current Raspberry Pis with a 40 pin GPIO header. The PiBreak Plus also includes a GPIO female header to solder yourself, and a pair of nuts, bolts, washers and spacers to ensure a a great fit.
And in the Freetronics fashion we've used a quality gold-plated (ENIG) PCB for durability, brought out all the power rails along with the GPIO next to the prototyping area to make adding circuits a breeze. Furthermore the pinouts are labelled on both the top and bottom of the PCB to save time referencing the right GPIO pins. For more information and to order - visit the PiBreak plus page now!
