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 hardware

As stated before, the hardware setting is quite simple. The relays array has already been set up in a previous chapter, while the infrared receiver circuitry is really tricky. So, let's go ahead!

Setting up the infrared detector

The infrared detector (or receiver) I used in this prototype is shown in the following image (actually, the receiver is the device with the red dot; the other one is just a transmitter that we're not using here).


The devices can be purchased at the following link (or by surfing the Internet):

The datasheet is available at


Note that the image shows the topmost part only of the infrared devices. In reality, they look similar to a normal diode.

The circuit to manage it is shown in the following diagram:

The infrared receiver (IR) is the diode with the red dot in the preceding diagram and R is a 6.8KΩ resistor. The following table...
