Learning Internet of Things

Explore and learn about Internet of Things with the help of engaging and enlightening tutorials designed for Raspberry Pi

Learning Internet of Things

About This Book
  • Design and implement state-of-the-art solutions for Internet of Things using different communication protocols, patterns, C# and Raspberry Pi
  • Learn the capabilities and differences between popular protocols and communication patterns and how they can be used, and should not be used, to create secure and interoperable services and things
  • A step-by-step hands-on tutorial with complete source code, that provides interoperable solutions for sensors, actuators, controllers, cameras, and protocol brides
Who This Book Is For
If you're a developer or electronics engineer who is curious about Internet of Things, then this is the book for you. With only a rudimentary understanding of electronics, Raspberry Pi, or similar credit-card sized computers, and some programming experience using managed code such as C# or Java, you will be taught to develop state-of-the-art solutions for Internet of Things in an instant.

In Detail
This book starts by exploring the popular HTTP, UPnP, CoAP, MQTT, and XMPP protocols. You will learn how protocols and patterns can put limitations on network topology and how they affect the direction of communication and the use of firewalls. Thing registries and delegation of trust are introduced as important tools to secure the life cycle of Things on the Internet. Once the fundamentals have been mastered, your focus will move to the Internet of Things architecture. A secure architecture is proposed that will take full advantage of the power of Internet of Things and at the same time protect end user integrity and private personal data without losing flexibility and interoperability.

This book provides you with a practical overview of the existing protocols, communication patterns, architectures, and security issues important to Internet of Things.

Help Your Kids with Computer Coding

Help Your Kids with Computer Coding

Take your kids from browsing to building the web with the latest in DK's award-winning Help Your Kids series: Help Your Kids With Computer Coding. Computer programming is one of the fastest-growing industries and highest paid college degrees, and learning to code promotes a way of thinking helpful for every budding brain. Yet 9 out of 10 schools don't even offer computer science classes to students, according to code.org. Help correct this disparity by introducing your kids to the world of computer programming early, with a fun and approachable method. This book begins by introducing the essential concepts of programming with simple instructions, and without specialized computer lingo. Fun projects throughout let kids start putting their computer skills into practice and build their own code using Scratch programming and Python, the two most popular languages. Also included are profiles on coding stars and insights in technology such as the Raspberry Pi mini computer. In typical DK fashion, colorful graphics and step-by-step instructions assist readers in starting to think like their computers.
