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 just stated, in this project we're trying to implement two different setups: the first one uses the analog output of the ultrasonic sensor and implements a circuitry, where all the devices are directly connected with the BeagleBone Black (all peripherals are near the board); on the other hand, the second setup allows us to remotely manage the ultrasonic sensor by using an USB connection, so we can mount the sensor far from the BeagleBone Black board.

Simply speaking, we can put the sensor in one place while the LEDs are in a different location, maybe in a more visible position, as shown in the following image:

As you can see, the dotted arrow, which represents the driver's point of view, is more clear if the LEDs are in a upper position with respect to the distance sensor that should be located near to the floor to better catch the car frontal.

First setup – all devices near the BeagleBone Black

In this setup, we're going to use an ADC pin of our BeagleBone Black...
