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.

Final test


To test the prototype, we must first select one setup and perform the needed connections, as stated before. Then we have to turn on the board.

After the login, we must setup the system by using the commands discussed before, or simply by using the chapter_02/SYSINIT.sh command in the book's example code repository. Then, we must execute the distance_mon.sh command accordingly.

Note

Note that looking into the SYSINIT.sh file, you can read:

# Uncomment the following in case of buggy kernel in USB host management
# cat /dev/bus/usb/001/001 > /dev/null ; sleep 1

This is if after plugging in the USB cable, you get an error in recognizing the /dev/ttyUSB0 device.

To test my prototype using the first setup, I used the following command:

root@beaglebone:~# ./distance_mon.sh -d -k 1.38 adc
distance_mon.sh: d_fun=read_adc k=1.38
distance_mon.sh: d=176
distance_mon.sh: d=175
distance_mon.sh: d=175
distance_mon.sh: d=175
distance_mon.sh: d=175
...

On the other hand, to test the second one, I...
