Charles Grant over at element14 put together this tutorial on basic IoT home automation using a BeagleBone Black and Drupal.
For those of you who have been following along with my BeagleBone Black and Drupal series, you could see this post coming. In my first installment I showed you how to build a website on the BeagleBone Black using the Drupal CMS, and followed it up with Controlling the BeagleBone Black’s GPIO Pins with Drupal. This tutorial is going to take things a step further and show you how to take that knowledge, and use it to trigger some relays to turn mains powered electronics on and off. While the method I am going to use would not be ideal for conrtolling an entire home, it works quite well for controlling things like props in a haunted house and other low-amperage things like small fans, lights, and such. Just to make things easier, I am going to recap a good bit of my previous tutorial here. You will still need to go through the Drupal setup steps in the first tutorial though.
Each Tuesday is BeagleBone Black Day here Adafruit! What is the BeagleBone? The BeagleBones are a line of affordable single-board Linux computers (SBCs) created by Texas Instruments. New to the Bone? Grab one of our Adafruit BeagleBone Black Starter Packs and check out our extensive resources available on the Adafruit Learning System including a guide to setting up the Adafruit BeagleBone IO Python Library. We have a number of Bone accessories including add-on shields (called “capes”) and USB devices to help you do even more with your SBC. Need a nice display to go along with your Bone? Check out our fine selection of HDMI displays, we’ve tested all of them with the Beagle Bone Black!
