The primary purpose of this book is to show the reader how to get the computer to interact with the physical world through additional hardware and programming. Although the book seems to be aimed at artists wanting to use the computer in their work, the principles taught can be of use to non-artists too. This book is broken down into two parts. The first, "The Basics", covers all aspects of computing in a very general sense. It is just an overview, and if you are such a beginner that you really need to know about electricity, what a microcontroller is, and what an "if statement" is in programming, you are likely going to need sources other than just this book. The last chapter in the section, "Communicating Between Computers" is the best of the basic chapters. This chapter talks about actual connectors and their pins, testing, and protocols and codes. All code shown in this book is in several flavors of the BASIC language, and the book does a pretty good job of getting you started. The section ends with a discussion on the specifics of serial communication on a multimedia computer. Part one has the following chapters and subsections:

In part two, the book demonstrates more advanced methods for accomplishing specific tasks. Most of these methods in part two are just special cases of the basic ideas in part one, and the book makes frequent reference to the circuits and code discussed in part one. There's really nothing here in the realm of specific projects. The book mainly talks about all of the various aspects of hardware and programming that are needed to interface a computer to the physical world. There is quite a bit of code and building-block circuitry shown for simple tasks that you can reuse in any larger project you decide to build.

I would say this is a good first book for anyone who is thinking about getting started with adding physical interfaces to their computer.

This is a perfect book. It teaches you, step-by-step with theory, code, examples and illustration, how to design and build your own microcontroller-based electronics projects. You can go from knowing nothing to being a relatively skilled amateur in just days. Futhermore, the book is amazingly comprehensive and covers so many complementary topics in addition to microcontrollers. This superb book answered almost every question (albeit basic) I ever had about electronics. Igoe and Sullivan, please write another book!!

This is a great overview of physical computing.. good for novices who aren't very technical, as well as for those who are more advanced.. basically the best ref out there for getting an overview of how to start building objects that you can interact with.. My background is in design-not computer science. I'd recommend for any designers, architects, filmmakers, etc. who interested in thinking about how to building and designing interactive installations or objects without need to know how to program. Great also for those with CS background, but this book is rare as it's written to span people with diffent degress of technical expertise... and one of the only references for people who aren't just geeks.

This book really is brilliant for someone wanting to get into programming circuits. I am coming from a computer programming background and wanted to make the move to physical computing. This book goes through every possible aspect and even gives the shopping list and possible stores for the items needed in the excercises. Even if you have no prior electronics or programming experience this book is the ticket.
Something to consider is the fact that the programming samples are all in the Basic language. If you want to learn to program microcontrollers in assembly then this book does not cover that.

This book is terrific, it could be used by a total novice in the field of electronics, and it can also serve as an excellent reference for advanced users. It explains basic principles extremely well and also gives many specific examples, including code for microcontrollers in several different programming languages. Well illustrated, with lots of strategies for designing projects as well as invaluable technical information, this is a great resource.

As a student at the NYU ITP program, I can personally attest to Tom and Dan's amazing knowledge. The physical computing program here is something that everyone can get a lot out of - even people with little programming or electronics experience are building interesting robotics and cutting edge projects.

I am an intermediate programmer/electronics person and I feel I have progressed to the point where I am building computer peripherals. It has opened up so many windows of opportunity for me.

Thanks Dan and Tom!

Great boek - very practical - general approach of connecting any device to a computer.
This book helped me very much in understanding and building the interaction between the pc and selfbuild electronic devices and sensors. It explanes the basics of programming, standard solutions, electronics, protocols. For me it was the ideal practical bridge between all my chaotic knowledge of techniques, standaards, practical skills...to make it coherent.
Because it aproaches the microprocessor from high level to low level, (plug and play packages versus the naked chip and resistors) and 4 different pic-manufactures it realy offers the basics an clarifies the direction where to look for your specific specialisation.

Maybe too much. At frst I found it difficult to tune into the examples for my platform (BX)among all the others (Stamp, Atom, PIC). I have been using their web sites for years. There is a lot of extra stuff here especially for beginners and also the mechanical and tracking stuff but I was happy paying 20 bucks (weirdly low price for a book with this much info) just to have those printed out.

I have been referring to both of the authors' web sites for a year or so now whenever I have some sort of technical problem to solve. I was elated to find out they had finally published this book and ordered it right away. This is the most comprehensive book on the subject of electronics and computation for artists and designers.

I bought an Arduino.
I went online and investigated how to use it through tutorials.
I learned about author Tom Igoe through some online videos and was fascinated by what he was doing with the Arduino.
I subsequently bought this book.
I was not disappointed.
Igoe and Sullivan use their teaching skills ..."teaching by doing," I think... to present a series of experiments on how to interface computers (specifically, microcontrollers) with the REAL world. Through the use of a variety of sensors (when I was in college we called them transducers), the authors illustrate how to "make things happen" based on what the sensors "sense".
This book uses the various incarnations of the PIC microcontroller. There is a wealth of information on the PIC and it is ubiquitous in robots, various types of device controllers, etc. But, I was particularly interested in using the Arduino controller board. So when I opened the book and found the authors' concentration on the PIC, I was disappointed to say the least. After a few pages, however, I found that the coverage was exactly what I was looking for. The programming, though NOT the Arduino Integrated Development Environment, was straightforward and revealing. I was able to translate easily from PIC Basic to Arduino sketches. And the coverage of the various kinds of sensors is fantastic!
This is a book about sensors. It is a book about how to utilize the data from sensors to control things in the real world. It is chock full of electronics, humor, projects and ideas. I recommend it highly to anyone getting started with the PIC microcontroller or the Arduino. This book is not for everyone, but if this is your interest, you money will be well spent.
