Overview of this book

BeagleBone is a microboard PC that runs Linux. It can connect to the Internet and can run OSes such as Android and Ubuntu. BeagleBone is used for a variety of different purposes and projects, from simple projects such as building a thermostat to more advanced ones such as home security systems. Packed with real-world examples, this book will provide you with examples of how to connect several sensors and an actuator to the BeagleBone Black. You’ll learn how to give access to them, in order to realize simple-to-complex monitoring and controlling systems that will help you take control of the house. You will also find software examples of implementing web interfaces using the classical PHP/HTML pair with JavaScript, using complex APIs to interact with a Google Docs account, WhatsApp, or Facebook. This guide is an invaluable tutorial if you are planning to use a BeagleBone Black in a home automation project.

Setting up the software

Now, it's time to set up the software to manage our infrared detector, and to do it, we're going to use the LIRC (Linux Infrared Remote Control) subsystem, which is a special code that has been developed for this purpose.


For further information on the LIRC subsystem, you can take a look at

We'll need a kernel driver to convert the pulse generated by the infrared detector into well-defined messages, and then to send them, through a LIRC device, to the userspace programs. At userspace level, we're going to use a special tool from the LIRC project in order to convert the infrared messages into input events, that is, the messages that a normal keyboard sends to the kernel.

Setting up the kernel driver

To set up the kernel driver to manage our infrared receiver, we can use a procedure similar to the one used in...
