BeagleBone Home Automation

By: Juha Lumme

Overview of this book

<p>Home automation lets you control daily activities such as changing the temperature, opening the garage door, or dimming the lights of your house using microprocessors. BeagleBone is a low-cost, high-expansion, hardware-hacker-focused BeagleBoard. It is small and comes with the high-performance ARM capabilities you expect from a BeagleBoard. BeagleBone takes full-featured Linux to places it has never gone before.</p> <p>Starting with the absolute basics, BeagleBone Home Automation gives you the knowledge you will require to create an Internet-age home automation solution. This book will show you how to set up Linux on BeagleBone. You will learn how to use Python to control different electronic components and sensors to create a standalone embedded system that also accepts control remotely from a smartphone.</p> <p>This book starts with the very basics of Linux administration and application execution using terminal connections. You will learn the basics of the general purpose input/output pins and discover how various electronic sensors and electronic components work. The “hardware jargon” is explained, and example applications demonstrating their practical use are created so that you will feel in control of the capabilities provided.</p> <p>Network programming is also a big part of this book, as the created server will be made accessible from the Internet through a smartphone application. You will also learn how to create a fully working Android application that communicates with the home automation server over the Internet.</p>

Chapter 5. Implementing Periodic Tasks

Our server is now capable of serving our clients with some environmental data, but it has no memory, and there is no way to alter its behavior without rewriting code. We will extend our server capabilities further in this chapter, and it will finally become a fully standalone server that will live its own life without the need for manual operation. We will also enhance our server-client interface so that the server can be operated and runtime configuration can be changed remotely with our client.

Of course, as always, we will also introduce new exciting hardware. In short, we will cover the following topics:

  • Adding a save/load framework for arbitrary data to our server

  • Creating configurable periodic tasks to our server

  • Adding interfaces to access data on the server to our client

  • Implementing remote reconfigurability to our server

  • New hardware: infrared motion sensor

  • Talk about "cape" extensions and integrate one to our Beagle

  • Adding support for the camera interface...
