Smart-Home-Systeme selber bauen Smart Home- und IoT-Technik für den Arduino bietet eine Fülle von Praxisprojekten, die mit einem einzigen Kit aufgebaut werden können. Das "SunFounder Smart Home Internet of Things Kit V2.0 for Arduino" enthält über 30 Komponenten, Bauelemente und Module aus allen Bereichen der modernen Elektronik. Damit lassen sich eine Fülle von Projekten realisieren. Für den Einsteiger werden zunächst einige einfachere Einsteigerexperimente vorgestellt. Der fortgeschrittenere Anwender kann sich dagegen gleich an die komplexeren Themen heranwagen. Neben präzisen digitalen Thermometern, Hygrometern, Belichtungsmessern und verschiedenen Alarmanlagen entstehen auch praktisch einsetzbare Geräte und Anwendungen wie etwa eine vollautomatische Beleuchtungssteuerung ein digitales Thermostat eine multifunktionale Klimamessstation Zudem wird detailliert erklärt, wie Messdaten in das Internet übertragen werden. Dort sind sie grafisch darstellbar und können weltweit abgerufen werden. Auch auf die damit verbundenen Gefahren und die Problematik des Datenschutzes wird eingegangen. Die vorgestellten Praxisprojekte bleiben dabei aber nicht im Status eines „Laborprototyps“ stehen. Durch entsprechende Tipps und Hinweise entstehen vielmehr praxistaugliche Geräte, die in Haushalt, Hobby und Beruf eingesetzt werden können. Selbstverständlich können sämtliche Bauteile auch einzeln beschafft werden, so dass sich die Projekte im Buch auch ohne das komplette IoT-Kit durchführen lassen.

ARM Cortex-M Embedded Design from 0 to 1 Hobbyists can mash together amazing functional systems using platforms like Arduino or Raspberry Pi, but it is imperative that engineers and product designers understand the foundational knowledge of embedded design. There are very few resources available that describe the thinking, strategies, and processes to take an idea through hardware design and low-level driver development, and successfully build a complete embedded system. Many engineers end up learning the hard way, or never really learn at all. ARM processors are essentially ubiquitous in embedded systems. Design engineers building novel devices must understand the fundamentals of these systems and be able to break down large, complicated ideas into manageable pieces. Successful product development means traversing a huge amount of documentation to understand how to accomplish what you need, then put everything together to create a robust system that will reliably operate and be maintainable for years to come. This book is a case study in embedded design including discussion of the hardware, processor initialization, low‑level driver development, and application interface design for a product. Though we describe this through a specific application of a Cortex-M3 development board, our mission is to help the reader build foundational skills critical to being an excellent product developer. The completed development board is available to maximize the impact of this book, and the working platform that you create can then be used as a base for further development and learning. The Embedded in Embedded program is about teaching fundamental skill sets to help engineers build a solid foundation of knowledge that can be applied in any design environment. With nearly 20 years of experience in the industry, the author communicates the critical skill development that is demanded by companies and essential to successful design. This book is as much about building a great design process, critical thinking, and even social considerations important to developers as it is about technical hardware and firmware design.
