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 8 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 9 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 5 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.
