I bought this book just after reading "Getting started with Arduino" - hoping that this book would enhance my knowledge enough that I would not break everything I plug into the Arduino with its Atmel Microcontroller.

Sofar it has been great. I have a degree in Computer Science, so some of the "This is a microprocessor, this is what makes it up" stuff was redundant for me, but this will not be the case for everyone.

The "Electronics 101" section is really helping me a lot - I don't have to pester my EE friend with nearly as many questions!

All of the topics could be easily found by a google search in much more details. The only good point after reading this book : a beginner knows how to pick from the smorgasbord of the Net.

Pretty useless for Engineers, even beginner Engineers already in the trade. And the book is not cheap !

I am a Firmware Engineer currently but have a degree in Electrical Engineering so I felt this book would help me relate my Electrical experience to the Firmware world. I was disappointed when I realized how basic this book was. They dedicate a full chapter to basic voltage, resister, capacitor, etc concepts. Even with no on the job experience outside of school I found almost nothing that I did not already know. It is good for people who need to learn the basics but if you have any computer architecture experience or electrical engineering experience then this book is not for you.

This is a practical introduction to embedded hardware, so to write software for the hardware presented in this book, you will need to consult other books. This book is only an introduction and if you want to gain more knowledge and experience in the field of hardware design, further study is required. In the first part of the book the author gives an introduction to computer architecture and describes the components that you find in a PC. The author goes on to explain basic electronics, just enough to understand the explanations about the electronic components. There are the basic equations to calculate voltage and current. The functionality of resistors, capacitors, inductors, diodes and crystals is explained. There is advice on how you can build or have built your own integrated circuit board. Some simple microprocessors and micro controllers are described including the currently available and commonly used PIC and AVR micro controllers, the 68000-series microprocessor and a DSP based controller. The functionality of the components is described and it is shown how the component can be used with a few other basic components to exercise a minimum of functionality. The book also covers useful topics like the protocols SPI (Serial Peripheral Interface) and I2C, Inter Integrated Circuit, which show how components can communicate with each other or the outside world. Various serial port and network protocols are discussed like RS232C and USB. Chapter 13 was particularly interesting, covering analog to digital conversion and applications. For example, the book explains how to use an amplifier to connect a digital circuit to a temperature or light sensor, or a motor control. The one thing I did not like about the book was the dedication of an entire chapter to the ancient language of Forth. This space might have been better spent on expanding the book's discussion of assembly language or the more timely topic of embedded networks.
This book might be too elementary for practicing engineers, particularly if they are already familiar with the devices commonly used in embedded circuits. However, for those engineers that have been writing software since they graduated, this book is a good fast-paced introduction to the hardware commonly found in embedded systems. A good follow-on to this book is "Programming Embedded Systems with C and C++" by the same publisher.

This is a great beginners book from basic electronics up to developing for specific chips. I've been an application developer for years and I've been looking to make the switch to lower level programming. This book will definitely get you started and even walk you through the design of the beginners microprocessors (PIC & AVR).
As mentioned above, it should have "beginner" in the title.
