About the Reviewer
David Whale is a software developer living in Essex, UK. He started coding as a schoolboy aged 11, inspired by the school science technician to build his own computer from a kit and quickly progressed to writing machine code programs because they were "small and fast". These early experiments led to some of his code being used inside a saleable educational word game when he was only 13.
He has been developing software professionally ever since, mainly writing small and fast code that goes into electronic products, including automated machinery, electric cars, mobile phones, energy meters, and wireless doorbells.
These days, he runs his own software consultancy called Thinking Binaries and spends nearly half of his time helping to design the next wave of the Internet called The Internet of Things, by connecting electronic devices to it. The rest of the time he volunteers for The Institution of Engineering and Technology, running training courses for teachers, designing and running workshops and clubs for school children, and being busy with his Raspberry Pi, BBC micro:bit and Arduino.
He was the technical editor for the book Adventures in Raspberry Pi and the co-author of the book Adventures in Minecraft, and is a regular reviewer and editor of technical books from a number of book publishers.
I was really pleased to be asked to review this great new book of projects using the Raspberry Pi Zero. The size of the Pi Zero makes it ideal for building into other products. In this book, Richard Grimmett takes us on an amazing journey of circuit bending, coding, and innovating using this tiny computer! But don't stop here; the projects in this book will give you the skills you need and inspire you to come up with many new ideas yourself!

Preface
For many years, robots and other advanced electronic wonders could only be seen on the television, movies, or in university or military labs. In recent years, however, the availability of new and inexpensive hardware and also free and open source software, has provided the opportunity for almost anyone with a little technical knowledge and imagination to build these technical wonders. The first wave of projects were fueled by Arduino, an inexpensive and simple-to-program microcontroller. The next wave was carried further by the introduction of the Raspberry Pi, an even more capable processor powered by the Linux operating system.
Now there is an even less expensive, powerful microprocessor: the Raspberry Pi Zero. This little processor packs a processor powerful enough to run Linux into a small and even less expensive package. This capability, coupled with some additional power, inexpensive hardware, and free open source software provides a platform for projects that range from simple wheeled robots to advanced flying machines.
What this book covers
Chapter 1, Setting Started with Raspberry Pi Zero, is designed to go through the details of setting up a useful development environment on Raspberry Pi Zero. The chapter begins with a discussion of how to connect power and continues through setting up a full system, configured and ready to be connected to any of the amazing devices and SW capabilities to develop advanced robotics applications.
Chapter 2, Programming Raspberry Pi Zero, reviews, for those who are already familiar, basic Linux, editing, and programming techniques that will be useful through the rest of the book. You'll learn how to interact from the command line, how to create and edit a file using an editor, and basic Python programming.
Chapter 3, Accessing the GPIO Pins on Raspberry Pi Zero, discusses the GPIO capabilities of Raspberry Pi Zero by building and controlling some simple LED circuits.
Chapter 4, Building and Controlling a Simple Wheeled Robot, discusses one of the amazing things you can do with Raspberry Pi Zero, controlling a simple wheeled robot. This chapter will show you how to add motor control, so you can build your very own autonomous mobile robot.
Chapter 5, Building a Robot That Can Walk, tells us about another impressive robotic project, an autonomous robot that can walk. This is done using servos whose position can be controlled using Raspberry Pi and some additional USB-controlled hardware.
Chapter 6, Adding Voice Recognition and Speech – A Voice Activated Robot, tells us about a voice-activated robot. One of the significant new features of today's computer system is the ability to input commands and provide output without a screen or keyboard. A few years ago, the concept of a computer that can talk and listen was science fiction, but today it is becoming a standard part of new cell phones. This chapter introduces how Raspberry Pi Zero can both listen to speech and also respond in kind. This is not as easy as it sounds (pun intended) and you'll be exposed to some basic functionality, while also understanding some of the key limitations. You'll take a standard toy and turn it into a responsive robot.
Chapter 7, Adding Raspberry Pi Zero to an RC Vehicle, tells us about another astounding capability of Raspberry Pi Zero, the ability to add "sight" to you projects. Raspberry Pi Zero makes this very easy by supporting open source software and readily available USB webcams. By adding this and a remote control, you can build a remote control vehicle that can go around corners, into rooms, wherever you'd like to go.
Chapter 8, Playing Rock, Paper, or Scissors with Raspberry Pi Zero, tells us about how we can use our toolkit to build and control a robotic hand that can see and respond to the world around it. In this case, you'll program your hand to play rock, paper, and scissors.
Chapter 9, Adding Raspberry Pi Zero to a Quadcopter, talks about the fact that building a robot that can walk, talk, or play air hockey is cool, but one that can fly is the ultimate goal.

Chapter 1. Getting Started with Raspberry Pi Zero
There has been a major shift in electronics and computer accessibility driven by the introduction of the Raspberry Pi microcomputer and its variants. With a completely different price point along with a significantly expanded support community, the Raspberry Pi has been an unprecedented success in bringing inexpensive computing to a wide audience. The Raspberry Pi Zero continues with that important approach, providing unprecedented computer power at an even lower price point.
The Raspberry Pi Zero is particularly useful as it can be paired with inexpensive hardware and open-source software to do a wide range of different Do-It-Yourself projects. You'll learn about many of these in this book. You'll learn how to control DC motors, how to control servos, how to hook up a microphone for speech recognition, and even how to connect a webcam to view and interpret the outside world.
The Raspberry Pi Zero can do amazing things, but first you'll need to understand how to access all of this capability. In this chapter, you'll learn how to:
Setting up the Raspberry Pi Zero
While the Raspberry Pi Zero is a powerful computer, you'll need some additional hardware to access this capability. Here are the items that you'll need for this chapter's projects:
Before you get started, let's get familiar with the Raspberry Pi Zero. Here is an image of the hardware:
Note that the GPIO pin male headers are not pre-soldered to the board; you'll want to do that. You can buy these at most online electronics retailers. You should also become familiar with the various connections on the board. Here, you can see the Raspberry Pi Zero with the connector soldered and the connections labeled for your information:
Powering the board
One of the first issues you'll want to consider is how to power the board. To do this, you need to connect through the USB power connection. There are two choices to provide power to the Raspberry Pi Zero:
In both cases, make sure that the unit can supply enough current. You'll need a supply that can provide at least 1000 mA at 5 volts. There are two USB charge connections on this battery which makes it easy to plug the Raspberry Pi Zero into one and the powered USB hub into the other. Do not plug in the board just yet, you first need to connect the rest of the hardware and configure the microSD card. However, you are now ready to connect the rest of the hardware.
Hooking up a keyboard, mouse, and display
The next step is to connect a keyboard, mouse, and display to the Raspberry Pi Zero. You may have much of this stuff already but, if you don't, there are some things to consider before buying additional equipment. Let's start with the keyboard and mouse.
To connect any device to the Raspberry Pi Zero you'll need some sort of adapter or hub. You can buy a simple hub that goes from the microUSB connector on the Raspberry Pi Zero to the more common standard connector. You can find these at most electronics online retailers, and it looks something like this:
However, there will be projects when you will want to connect more than one device to the Raspberry Pi Zero. For these cases you may want to consider purchasing a powered USB hub. Before deciding on the hub to connect to your board, you need to understand the difference between a powered USB hub and one that gets its power from the USB port itself.
