Phadke About the Author Pratik Desai, PhD, is the Principal Scientist and cofounder of a connected devices start-up, Imbue Labs, where he develops scalable and interoperable architecture for wearable devices and Internet of Things (IoT) platforms during the day At night, he leads the development of an open source IoT initiative, the Semantic Repository of Things Pratik has years of research and design experience in various layers of the IoT and its predecessor technologies such as wireless sensor networks, RFID, and machine-to-machine (M2M) communication His domains of expertise are the IoT, Semantic Web, machine learning, robotics, and artificial intelligence Pratik completed his MS and PhD from Wright State University, Ohio, and collaborated with the Ohio Center of Excellence in Knowledge-enabled Computing (Kno.e.sis) during his doctoral research His doctoral research was focused on developing situation awareness frameworks for IoT devices, enabling semantic web-based reasoning and handling the uncertainty associated with sensor data In his personal life, Pratik is an avid DIY junkie and likes to get hands-on experience on upcoming technologies He extensively expresses his views on technology and shares interesting developments on Twitter (@chheplo) I would like to dedicate the book to my parents, who were responsible for building the foundation of what I am today The book would not have been possible without the patience, support, and encouragement from my beloved wife, Sachi I would also like to thank her for landing her photography skills that were used in development of some of the important images used in the book I would also like to extend my sincere gratitude to the editors for their valuable feedbacks About the Reviewers Juan Ramón González is a technical engineer of computer systems and lives in Seville (Andalusia, Spain) For the past years, he has been working on free software-based projects for the regional Ministry of Education by using Python, C++, and JavaScript, among other programming languages He is one of the main members of the CGA project in Andalusia (Centro de Gestión Avanzado or Advanced Management Center), which manages a network with more than 4,000 servers with Debian and 500,000 client computers that run Guadalinex, a customized Ubuntu-based operating system for Andalusian schools As a software developer who has a passion for electronics and astronomy, he started one of the first projects to control a telescope with the Arduino microcontroller by using a computer with the Stellarium software and a driver developed with Python to communicate with the telescope This project's sources are published on the collaborative platform GitHub You can see the whole code and the prototype at https://github.com/juanrmn/Arduino-Telescope-Control Marco Schwartz is an electrical engineer, entrepreneur, and blogger He has a master's degree in electrical engineering and computer science from Supélec, France, and a master's degree in micro engineering from EPFL, Switzerland Marco has more than years of experience working in the domain of electrical engineering His interests gravitate around electronics, home automation, the Arduino and the Raspberry Pi platforms, open source hardware projects, and 3D printing He runs several websites around Arduino, including the Open Home Automation website that is dedicated to building home automation systems using open source hardware Marco has written a book on home automation and Arduino called Arduino Home Automation Projects, Packt Publishing He has also written a book on how to build Internet of Things projects with Arduino called Internet of Things with the Arduino Yun, Packt Publishing Josh VanderLinden is a lifelong technology enthusiast who has been programming since the age of 10 He enjoys learning and becoming proficient with new technologies He has designed and built software, ranging from simple shell scripts to scalable backend server software to interactive web and desktop user interfaces Josh has been writing software professionally using Python since 2007, and he has been building personal Arduino-based projects since 2010 www.PacktPub.com Support files, eBooks, discount offers, and more For support files and downloads related to your book, please visit www.PacktPub.com Did you know
