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

This time, to implement the software of this prototype, we can use a state-machine with the following states and their relative transactions:

State

Description

Actions

Transaction conditions

IDLE

Idle state; the washing machine is not working.

  • LED yellow off

  • LED red off

  • If sound is detected, set t0=t and move state to SOUND.

SOUND

Sound detected! Keep monitoring the environment for a while.

  • LED yellow is blinking

  • LED red is off

  • If sound is detected and t-t0 > timeout, move to RUNNING.

RUNNING

Continuous sound detected so the washing machine has started its job.

  • LED yellow is on

  • LED red is off

  • Alert the user

  • If no sound is detected, set t0=t and move to NO_SOUND.

NO_SOUND

No more sound detected! Keep monitoring the environment for a while.

  • LED yellow is on

  • LED red is blinking

  • If no sound is detected and t-t0 > timeout, move to DONE.

  • If sound is detected, move to RUNNING.

DONE

No more sound for a long delay; the washing machine has finished...
