A remote-controlled doorbell with Raspberry Pi and node.js

Thanks to the ease of adding Internet-based connectivity to a Raspberry Pi, it lends itself to all sorts of remote-control and data gathering applications. One example of this is by Arvind Ravulavaru who has documented controlling a Raspberry Pi not only as a local doorbell, but one that can be controlled over the net via node.js and python.

The resulting project simply controls a GPIO pin from a remote, web-enabled device - however thanks to the clarity of Arvind's work you can use this as a framework for all sorts of applications. A quick demonstration of the remote doorbell is shown in the following video:

For all the code and an interesting tutorial, visit Arvind's website. And for more, we're on facebookGoogle+, and twitter - so follow us for news and product updates as well.

If you need to connect external circuitry to your Raspberry Pi such as the project above, consider our PiBreak board. It provides labelled breakout pins for all GPIOs, a large prototyping area with solder pads, and power rails for easy power connection:

Furthermore the PiBreak also includes mounting hardware to firmly attach it to your Raspberry Pi using a nut, bolt, and spacer - and is compatible with all revisions of both model A and B Raspberry Pi computers. For more information about our PiBreak board, our Getting Started guide, and to order - visit the product page.
