Take your idea from concept to production with this unique guide

Whether it's called physical computing, ubiquitous computing, or the Internet of Things, it's a hot topic in technology: how to channel your inner Steve Jobs and successfully combine hardware, embedded software, web services, electronics, and cool design to create cutting-edge devices that are fun, interactive, and practical. If you'd like to create the next must-have product, this unique book is the perfect place to start.

Both a creative and practical primer, it explores the platforms you can use to develop hardware or software, discusses design concepts that will make your products eye-catching and appealing, and shows you ways to scale up from a single prototype to mass production.

  • Helps software engineers, web designers, product designers, and electronics engineers start designing products using the Internet-of-Things approach
  • Explains how to combine sensors, servos, robotics, Arduino chips, and more with various networks or the Internet, to create interactive, cutting-edge devices
  • Provides an overview of the necessary steps to take your idea from concept through production

If you'd like to design for the future, Designing the Internet of Things is a great place to start.














by more than a month, and then a smaller issue in assembly with the magnetic catches on the case delayed things by another week or so. At the end of November 2012, these playful Little Printers started winging their way out to customers, bringing more Internet of Things goodness into numerous homes. Certification One of the less obvious sides of creating an Internet of Things product is the issue of certification. If you forget to make the PCB or write only half of the software for your

new selection to the server took less than a second, it was still long enough for subsequent button presses to be missed if you were running through them quickly. Given that the end of the day was looming large, and as I would be able to talk around the issue in the demonstration, I chose expediency over the larger amount of coding required to decouple the user interface of buttons from the network communication. A “busy” LED was added to the breadboard and illuminated whenever the Arduino was

Prototyping the Physical Design Chapter 7: Prototyping Online Components Chapter 8: Techniques for Writing Embedded Code 1 The Internet of Things: an Overview The first question that we should attempt to answer is, of course, what is the Internet of Things? Although the concepts we call on throughout this book are relatively straightforward, people have many different visions of what the phrase means, and many of the implications are hard to grasp. So we will take this question slowly in

USR3 with one of the standard pins, such as P8_3. As with Python, JavaScript is a high-level language, so after you move beyond the physical input and output with electronic components, tasks dealing with text manipulation, talking to Internet services, and so on are far easier to handle than the relatively low-level C++ used in the Arduino. And again, Node.js is a rich environment with a host of libraries available to integrate into the app. Currently, the convenient npm (Node Packaged

requests, even if the higher-level code isn’t doing what you expect. If you know the IP address of the device and it responds when you query it with the ping network utility, you can infer that at least some part of the system is still functioning. Taking that thinking further, if you can connect a computer somewhere on the network path between the device and the service it communicates with, running a packet sniffer enables you to see what is happening at the network level.
