About the Reviewers

Jimmy Hedman is a professional high performance computing (HPC) geek who works with large systems where size is measured in number of racks and cores. In his spare time, he goes in the opposite direction and focuses on smaller things, such as BeagleBone Blacks and Arduinos. He is currently employed by South Pole AB, the biggest computer server manufacturer in Sweden, where he is a Linux consultant with HPC as his main focus. This is the first book Jimmy has worked on, but hopefully not the last.

I would like to thank my understanding wife who lets me go on with my hobbies like I do. I would also like to thank Packt Publishing for letting me have this much fun with interesting stuff to read and review, and not to forget, Stockholm Robotförening (Stockholm Robot Club), which opened my eyes to how easy it is to actually build a robot.

Pradumn Joshi is currently pursuing his Bachelor's degree in Electrical Engineering from NIT, Surat. He is an avid elocutionist, tinkerer, and debate enthusiast. He is also interested in economics, freelance writing, and western music. His area of technical interest lies in open source hardware development and embedded systems.

I would like to thank my best friends and brothers, Rahul and Parikshit.

Sudar Muthu builds robots as a hobby, and Arduino is his playground. He discovered the joy of hardware programming through Arduino around 4 years back, and since then, he has been using it for his various pet projects. He has created a lot of libraries for Arduino and also currently maintains a Makefile for Arduino that helps you do professional Arduino development.

He conducts workshops about Arduino and robotics and has given talks at various conferences about hardware programming. He blogs about his experience in hardware programming and also about his various projects at http://hardwarefun.com.

I would like to dedicate this book to my parents, who gave me life, to my wife, who made it happier, and to my son, Arul, who made it worth living.
