Amazon calculates a product’s star ratings based on a machine learned model instead of a raw data average. The model takes into account factors including the age of a rating, whether the ratings are from verified purchasers, and factors that establish reviewer trustworthiness.
The soldering advise is completely WRONG. Find better instructions! When he tells about lighting LEDs, then he sets down some code and says this is what you will use, however on the next page he shows you how that coding is wrong. Later mentions resistor colors and codes, but doesn't list them, but gives 2 examples which isn't enough to understand. Then later page he says that the pins on the UNO were discussed earlier, and that discussion did not take place in the book. That's what I bought the book for and what I expected to be in a beginner's book. There are what appears to be useful examples in the last half of the book, as long as what's coming is better than the first half. That is also a major part of understanding the uses the device can be put to. So, my review is on whether or not this book is instructive to a beginner, and I have to say it is not.
As a novice to electronics and Arduino, I was really disappointed in this book. Most beginners learn by example and visual layout (figures or pictures of how it works). This was lacking in this book. For example a simple layout of how a breadborad works, how the connections connect to each other. I've bought another book that explains things in greater detail, which I've included a picture of how the board is explained). I would not recommend this book for a beginner.
