Introduction
T
HIS IS A PROJECT BOOK
that marries together the simple-to-use microcontroller boards (Arduino) and
the world of Android mobile phones and tablet computers.
The book contains detailed instructions for constructing various projects that use Arduino and
Android devices. Some of the projects, such as the Geiger Counter and the Ultrasonic Distance Meter, are
essentially electronic accessories for your Android phone.
Other projects in the book work toward a home automation system, complete with electric door lock
and a remote control for power and heating, making even home automation accessible from the Internet
and your Android device.
Arduino
Arduino (
Figure 1
) is a small microcontroller board with a USB plug to connect to your computer and a
number of connection sockets that can be wired up to external electronics such as motors, relays, light
sensors, laser diodes, loudspeakers, microphones, and other items. They can either be powered through
the USB connection from the computer, or from a battery or other power supply. They can be controlled
from the computer or programmed by the computer and then disconnected and allowed to work
independently.

The board design is open source. This means that anyone is allowed to make Arduino-compatible
boards. Such competition has led to low costs.
The basic boards are supplemented by accessory shield boards that can be plugged on top of the
Arduino board. In this book, we will use three shields: the USB master shield that allows us to connect to
Android devices over USB; a motor shield for driving the wheels of a little robot; and an Ethernet shield

that will allow us to turn our Arduino into a tiny web server.
The software for programming your Arduino is easy to use and also freely available for Windows,
Mac, and Linux computers, at no cost.
Android
Android is Google’s phone and tablet operating system. Developing for Android is free. The software
development tools are free and there are no fees associated with distributing your app. You can also
deploy directly without having to use Google’s Market.
Apps for all the Android projects in the book, such as the one shown in
Figure 2
, are available for
download from the book’s web site at
www.duinodroid.com
. However, should you wish to modify the
apps, the source code is also freely available from the web site.
