Arduino Internals guides you to the heart of the Arduino board. Author Dale Wheat shares his intimate knowledge of the Arduino board—its secrets, its strengths and possible alternatives to its constituent parts are laid open to scrutiny in this book. You'll learn to build new, improved Arduino boards and peripherals, while conforming to the Arduino reference design.

Arduino Internals begins by reviewing the current Arduino hardware and software landscape. In particular, it offers a clear analysis of how the ATmega8 board works and when and where to use its derivatives. The chapter on the "hardware heart" is vital for the rest of the book and should be studied in some detail.
Furthermore, Arduino Internals offers important information about the CPU running the Arduino board, the memory contained within it and the peripherals mounted on it. To be able to write software that runs optimally on what is a fairly small embedded board, one must understand how the different parts interact. Later in the book, you'll learn how to replace certain parts with more powerful alternatives and how to design Arduino peripherals and shields.

Since Arduino Internals addresses both sides of the Arduino hardware-software boundary, the author analyzes the compiler toolchain and again provides suggestions on how to replace it with something more suitable for your own purposes. You'll also learn about how libraries enable you to change the way Arduino and software interact, and how to write your own library implementing algorithms you've devised yourself. Arduino Internals also suggests alternative programming environments, since many Arduino hackers have a background language other than C or Java.
Of course, it is possible to optimize the way in which hardware and software interact—an entire chapter is dedicated to this field.
Arduino Internals doesn't just focus on the different parts of Arduino architecture, but also on the ways in which example projects can take advantage of the new and improved Arduino board. Wheat employs example projects to exemplify the hacks and algorithms taught throughout the book.

Arduino projects straddling the hardware-software boundary often require collaboration between people of different talents and skills which cannot be taken for granted. For this reason, Arduino Internals contains a whole chapter dedicated to collaboration and open source cooperation to make those tools and skills explicit.

One of the crowning achievements of an Arduino hacker is to design a shield or peripheral residing on the Arduino board, which is the focus of the following chapter. A later chapter takes specialization further by examining Arduino protocols and communications, a field immediately relevant to shields and the communication between peripherals and the board.

Finally, Arduino Internals integrates different skills and design techniques by presenting several projects that challenge you to put your newly-acquired skills to the test!

Beginning Arduino Programming allows you to quickly and intuitively develop your programming skills through sketching in code. This clear introduction provides you with an understanding of the basic framework for developing Arduino code, including the structure, syntax, functions, and libraries needed to create future projects. You will also learn how to program your Arduino interface board to sense the physical world, to control light, movement, and sound, and to create objects with interesting behavior.
With Beginning Arduino Programming, you'll get the knowledge you need to master the fundamental aspects of writing code on the Arduino platform, even if you have never before written code. It will have you ready to take the next step: to explore new project ideas, new kinds of hardware, contribute back to the open source community, and even take on more programming languages. What you’ll learn Start programming quickly with Arduino sketches. Write code that interacts with devices, such as LEDs, sensors, and motors. Work with loops, functions, randomness, and delays in your Arduino projects. Develop a style of writing code that reflects your individuality. Use many of the Arduino libraries to control even more devices. Read from RFID readers, write data to SD memory cards, and connect to the Internet using Ethernet. Who this book is for

This book is for all Arduino board users who want to learn to program the Arduino board, regardless of hardware version or which devices are connected to the board. You do not need to have programmed before, but if you have, then you'll learn how to apply core coding features in the Arduino context.

Arduino Projects to Save the World shows that it takes little more than a few tools, a few wires and sensors, an Arduino board, and a bit of gumption to build devices that lower energy bills, help you grow our own food, monitor pollution in the air and in the ground, even warn you about earth tremors.

Arduino Projects to Save the World introduces the types of sensors needed to collect environmental data—from temperature sensors to motion sensors. You'll see projects that deal with energy sources—from building your own power strip to running your Arduino board on solar panels so you can actually proceed to build systems that help, for example, to lower your energy bills. Once you have some data, it's time to put it to good use by publishing it online as you collect it; this book shows you how.

The core of this book deals with the Arduino projects themselves:

Account for heat loss using a heat loss temperature sensor array that sends probes into every corner of your house for maximum measurement. Monitor local seismic activity with your own seismic monitor. Keep your Arduino devices alive in the field with a solar powered device that uses a smart, power-saving design. Monitor your data and devices with a wireless radio device; place your sensors where you like without worrying about wires. Keep an eye on your power consumption with a sophisticated power monitor that records its data wherever you like.

Arduino Projects to Save the World teaches the aspiring green systems expert to build environmentally-sound, home-based Arduino devices. Saving the world, one Arduino at a time.

Arduino Adventures: Escape from Gemini Station provides a fun introduction to the Arduino microcontroller by putting you (the reader) into the action of a science fiction adventure story. You'll find yourself following along as Cade and Elle explore Gemini Station—an orbiting museum dedicated to preserving and sharing technology throughout the centuries.

Trouble ensues. The station is evacuated, including Cade and Elle's class that was visiting the station on a field trip. Cade and Elle don’t make it aboard their shuttle and are trapped on the station along with a friendly artificial intelligence named Andrew who wants to help them get off the damaged station. Using some old hardware, a laptop, and some toolboxes full of electronics parts, you will follow along and build eight gizmos with Cade and Elle that will help them escape from Gemini Station.

The hardware is Arduino. Each new challenge opens a new area of Arduino and basic electronics knowledge. You’ll be taken incrementally from a simple task such as turning on a light through to a complex combination of microcontroller, electronic components, and software programming. By the end of the book you’ll be well on your way towards being able to create and implement any sort of electronically controlled device you can imagine, using the stunningly popular Arduino microcontroller.

Provides eight challenges, each challenge increasing in complexity Builds around a fictional storyline that keeps the learning fun Leaves you on a solid foundation of electronic skills and knowledge
Arduino boards have impressed both hackers and professional engineers. Whether you're a hobbyist or a professional, it isn't just a breadboard and a hazy idea that keeps you going. It's essential to institute a proper design, device instrumentation and, indeed, test your project thoroughly before committing to a particular prototype.

Practical Arduino Engineering begins by outlining the engineering process, from the basic requirements and preliminary design to prototyping and testing. Each and every chapter exemplifies this process and demonstrates how you can profit from the implementation solid engineering principles—regardless of whether you just play in your basement or you want to publicize and sell your devices.

Arduino is a brilliant prototyping platform that allows users to test and iterate design ideas. Imitation by other Arduino makers, hackers and engineers often proves your design's popularity. Practical Arduino Engineering will teach you to follow the engineering process carefully; over time, you will be able to review and improve this process, and even extend its scope.

Practical Arduino Engineering is not purely theoretical. In addition, you'll learn the process of hardware engineering as applicable to Arduino projects, and the importance of the process in each and every project presented in this book.

To set the stage, Practical Arduino Engineering begins by reviewing the Arduino software landscape, then shows how to set up an Arduino project for testing. Even if you already know your compiler toolchain and the basics of Arduino programming, this refresher course can help fill in the gaps and explain why your compiler may spit out certain error messages.

Practical Arduino Engineering then gradually builds up the engineering process, from single devices like LCDs, potentiometers and GPS modules, to the integration of several modules into larger projects, such as a wireless temperature measurement system, and ultimately an entire robot.

The engineering projects become progressively more challenging throughout the first 4 engineering chapters. Next, you'll proceed with simple steps towards the first intelligent part of a robot: the object detector. You'll find yourself teaching your robot how to avoid very hot objects or insurmountable obstacles. The basic design requirements for a complete robot and, indeed, the detailed design and prototyping for robots can be extremely tricky, which is why engineering discipline is invaluable.

Practical Arduino Engineering then enters the world of domestic engineering by introducing home alarm systems—not quite as simple as they seem. A solid, robust system can only be built by following the engineering process detailed in previous chapters, and this section reinforces that process.

You'll then take a step further in your Arduino engineering process: instrumentation and control, and some error messaging using GSM. Control is introduced via the Xbox controller, a very powerful piece of technology able to play a considerable role in robotics projects. Having already learned to control motion and to sense and avoid objects, you'll learn how to debug your Arduino projects of varying complexities via the hardware instrumentation software LabVIEW.

To complete the journey into Practical Arduino Engineering, you'll discover how to use a special Arduino board to rely on Bluetooth Mate Silver for control of domestic and mobile Arduino projects. Using Bluetooth Mate Silver, you'll learn to implement basic engineering design with almost any Arduino project, and be able to justify, build, debug, and extend Arduino-based designs using a solid engineering approach.
