Beginning Arduino ReviewFinally, somebody got it right! I have to agree with Mr. Young and Mr. Laefsky's reviews, but feel that I should add just a bit more.
There are plenty of books out there on Arduino and I own or have examined most of them, so I thought my Arduino Library was full. I was wrong, this one was under the tree for Christmas and it's definitely a keeper. I read the book all the way through and then I started working through the activities early yesterday morning. Having now completed the projects through Chapter 3, I feel competent to review it.
The bottom line is that if you are starting out with Arduino and have been trying to piece together your skills from web tutorials and a few of the popular books, but have felt either out of your depth reading Making Things Talk: Practical Methods for Connecting Physical Objects, or that the material in, for example Getting Started with Arduino (Make: Projects) is too basic, this is the book that will vault you to the next level.
Books and tutorials on Arduino generally seem to trend toward two extremes:
On the one hand there is the "box of crayons" approach- tutorials (see practically every website of every vendor that sells Arduino and variants) that give very short and specific instructions on how to wire one or two components to Arduino and interact with them via a brief, illustrative, but not especially useful code example. These examples are intended, I guess, to give the reader some general ideas of the creative uses for Arduino, and the code snippets and discrete components are treated individually like crayons in the box of 64, with little guidance as to how they can be combined and blended together to make amazing and wonderful creations, or why you might choose one method of blinking an LED over another.
On the other hand, there is the pet project approach. These present someone's grand idea for a complex interactive project, usually costly, usually inspirational, but usually ill suited as a learning platform. You indeed can learn a tremendous amount by following along and building the projects in, for example, Practical Arduino: Cool Projects for Open Source Hardware (Technology in Action), and I did. But unless you actually WANT an internet connected, GPS enabled, refrigerator monitor (I'm making that up), you will end up spending a lot of extra time and money to nail down the knowledge to design your data logging cell phone seeker robot (I'm making that up too).
Beginning Arduino takes a third path. The projects are designed to be wired up on a breadboard with mostly reusable, reasonably priced components. You will not end up soldering something together only to realize that you are going to have to buy another one for the next phase in your learning. Each project is a bit more complex than the one preceding, but in each case the code and the hardware added push off into new areas and new uses. Once you complete a particular project, and the suggested exercises, you have a clear understanding of how the new component works and what you can do with the new code you learned. For me this lead to a much clearer understanding of how I could approach the challenges in my own pet project.
Before I started reading and working through Beginning Arduino, I had about decided that I would never grok C programming, feel comfortable with Arduino, or meet my ultimate goal of embedding Atmel chips in a variety projects floating around in my imagination. But over the past few days my enthusiasm and confidence have returned and I thank Mr. McRoberts for that.
One final note, while there are a few minor typographical errors, I can report that so far there has not been a single error that has interfered with the completion of a functional project. This is, in my experience, rare in a book with such technical depth. I applaud Mr. McRoberts and his technical reviewer, Josh Adams for such a fine job.Beginning Arduino Overview

Robot Building for Beginners ReviewI'm an Electrical Engineer at U.C. I bought this book so I could learn some "real world knowledge" about the physical world instead of just theory. I only asked for (and thankfully received) a multimeter, soldering iron, and a cordless dremel drill for Christmas. After reading this book, I now remember why I chose my major--making a robot is a blast!
Being strong on the theory, I didn't learn anything in that regard. On the flip side, David Cook described the basics in a way that anyone could understand. What I really wanted to learn was to be able to put my Christmas presents to use. He spent a chapter just on the multimeter! I loved it. Also, every part of the robot was described in detail. I now know the difference between choosing motors, batteries, transistors, comparitors, diodes, potentiometers, photo-resistors, ect.
When I brought my first creation into my Electromagnetics class yesterday, I of course was asked to give a demonstration. From reading this book (to be honest a total of 3 times), I described everything about it in clear/consise detail. The only part I failed was receiving extra credit. Yes I did try :D.
I couldn't imagine a better book for beginners. There is a website that describes the robot AND the few typos caught (nothing that mattered), ways he took this idea and added a couple more in a similar project, as well as detailing the post construction of robots he's made since then. Cook goes into detail for troubleshooting a potential screw up you may make (If 'X' is happening then you probably did 'Y'). Yes I made one too--thanks for asking.
There is one part I didn't like about the project though--using an M&M's Mini tube to hold the motors. Being so close to Valentine's day, the only selection they had were PINK ones! Oh well, I named in Valentino anyway. I did find myself telling this story though to everyone that commented on my pink robot.
If you want to get into the hobby, buy this book. You can't ask for more. Just be prepared to catch yourself looking in the toy section of Target for lego technic tires when your fiance is wanting to register!!! BTW: you'll also catch yourself babbling on about your experiences in a review about this book too--cause you'll be so D@MN excited about making your first robot!!!Robot Building for Beginners OverviewLearning robotics by yourself isnt easy. It helps when the encouragement comes from someone whos been there. Not only does "Robot Building for Beginners" assist you in understanding component parts of robot development, but also it prepares you with techniques to learn new discoveries on your own. Author David Cook begins with the anatomy of a homemade robot and gives you the best advice on how to proceed successfully. General sources for tools and parts are provided in a consolidated list, and specific parts are recommended throughout the book. Also, learn basic safety precautions and essential numbering and measuring systems. An in-depth analysis of digital multimeters gives you all the information you need to select and obtain this valuable tool for yourself. Other tools and parts covered include: motors, wheels, resistors, wire strippers, needle nose pliers, tap and die, alligator clips, LEDs, solderless breadboards, soldering irons, heat-shrink tubing, photoresistors, transistors, chips, gears, nut drivers, screws, cut-off wheels, connectors, and batteries. "Robot Building for Beginners" is an inspiring book that provides basic, practical knowledge on getting started in amateur robotics. Author InformationDavid Cook - David Cook is an engineering section manager at Motorola. He has 20 years of experience as a software developer, creating everything from award-winning computer games to mobile background-check applications for police. Having self-taught himself electronics and basic mechanics, he comfortably relates his recent years of robot experiences to the average backyard scientist, without scholarly intimidation.

Building Robots With Lego Mindstorms : The Ultimate Tool for Mindstorms Maniacs ReviewI am not ashamed to admit that I am 28-going-on-29 and I absolutely love this book. It is very well written and highly detailed. As a Mehanical Engineer with 6+ years work experience I was certain that this book wouldn't live up to the expectations that the first few pages that I read in the book store led me to develop. Was I wrong!! This book's simplified expanation of engineering concepts is unmatched. From Lego block geometry to gearing setup and programming. This book has it all if you'd like to go beyond the few missions that the mindstorm kit comes with. Don't be mistaken this book has no step-by-step instructions for building robots. It only introduces "snippet" to get your creative "juices" flowing. My understanding of Legos and their use has been greatly enhanced. To make things even better, the authors includes useful information on other Lego parts that are not included with mindstorm that are very important, i.e. light sensors, hydraulics, etc. If you are looking for a reference book to help you build better Lego creations, this book is it!!Building Robots With Lego Mindstorms : The Ultimate Tool for Mindstorms Maniacs OverviewLego robots! Mindstorms are sweeping the world and fans need to learn how to programme them Lego Mindstorms are a new generation of Lego Robots that can be manipulated using microcomputers, light and touch sensors, an infrared transmitter and CD-ROMs. Since Lego launched Lego Mindstorms in late 1998 sales have skyrocketed - with no sign of slowing down. Mindstorms have captured the imagination of adults and children alike, creating a subculture of Mindstorm enthusiasts around the world. The kits are now a staple part of engineering and computer science classes at many high profile Universities.Building Robots with Lego Mindstorms provides readers with a fundamental understanding of the geometry, electronics, engineering, and programming required to build your own robots. Mario and Giulio Ferrari are world-renowned experts in the field of Lego Mindstorms robotics, and in this book they share their unrivaled knowledge and expertise of robotics as well as provide a series of chapters detailing how to design and build the most exotic robots. Mario and Giulio also give detailed explanations of how to integrate Lego Mindstorms kits with other Lego programmable bricks such asScout and Cybermaster,as well as with non-robotic Lego Technics models.

Creating Cool MINDSTORMS NXT Robots (Technology in Action) ReviewIf you're searching for some exciting NXT projects and ideas--or would simply like to build JohnNXT, a replica of the famous Johnny 5 robot--you will enjoy Daniele Benedettelli's book Creating Cool MINDSTORMS NXT Robots. The book presents helpful ideas that you can use in your own inventions and carefully integrates them in a variety of robots with detailed building instructions. In fact, these very features are why I've given the book five stars: challenging robot projects, excellent discussions of useful concepts and ideas, and exceptional building instructions.
Most of the robots seem intended for more advanced users looking for a challenge; in other words, these are generally more complex robots. For example, there are several walking robots--including three bipeds (two-legged robots), one of the most difficult types of robots to create. And with the exception of the massive, multi-NXT robot "JohnNXT" (chapter 8) and a remote control (chapter 9), you can build all the robots from the parts in a single retail LEGO MINDSTORMS NXT set. All the programming in the book is done in NXC (Not eXactly C), an unofficial text-based language with a C-like syntax.
Along the way you'll find in-depth explanations of robotics concepts and helpful descriptions of the robots. Besides an entire "theory chapter" on building biped robots (chapter 1) and another such chapter on finite state machines (chapter 3), the robot chapters themselves include explanations of concepts such as hysteresis, writing a multitask program, and quadruped (four-legged) walking as well as information on the robots' functionality and history. The author also does a good job of presenting and explaining the programming. Although prior NXC experience is helpful, such experience is not required.
The BIs (building instructions) are outstanding, which is important since they are a major part of the book. The author used advanced BI techniques, including complete electrical cables and callouts, and Ldglite to render the images, creating BIs that are remarkably "LEGO-like." I found that the BIs were generally very easy to follow even though many of the steps were complex. Such clarity is invaluable for a book that is filled with building instructions.
I admit that I didn't build the famed JohnNXT robot. Why? For starters, I don't have all the necessary pieces! All the same, I'm glad to see that the author included the robot because a number of readers will want tackle this enormous project.
In conclusion, this book is ideal for you if you're a more experienced NXT user looking to broaden your robotic horizons--while having lots of fun. Nevertheless, even if you're new to the NXT set, you would still enjoy the book. Either way, after working through the projects and grasping the concepts, you should be well-equipped to create your very own cool NXT robots.
Creating Cool MINDSTORMS NXT Robots (Technology in Action) OverviewThis book teaches anyone interested how to build LEGO MINDSTORMS robots. He starts with an easy robot and gets to more detail in the succeeding 6 robots built in the book. The robots he presents are award winning robots, so he is giving away his secrets. He also teaches how to program the robots. If you are not a programmer, then you can use the code provided. He tells you what equipment you need and how to get it inexpensively. So everything is discussed that you will need to create these robots or modify his designs to create your own.
