Chapter 7. Build Your Own Home Automation System

So far in this book, we have used only already-assembled Arduino boards and interfaced them with different sensors and modules to build home automation projects. In the previous chapter, we changed things a bit and hacked a commercial device using Arduino.

However, in this last chapter of the book, we are going to take things further and build our own system for home automation. As an example, I will take the design and fabrication of a very simple low-power Arduino board. This board can then be used for home automation projects such as battery-powered motion sensors.

Note that the goal of this last chapter of the book is really to give you a step-by-step method to build your own home automation systems. Therefore, you should not focus on the specific example that is developed in this chapter, but more on the overall methodology to design your own systems.

The following will be the major takeaways from this chapter:
