Mastering the I²C Bus takes you on an exploratory journey of the I²C Bus and its applications. Besides the Bus protocol, plenty of attention is given to the practical applications and designing a stable system. The most common I²C compatible chip classes are covered in detail. Two experimentation boards are available that allow for rapid prototype development. These boards are completed by a USB to I²C probe and a software framework to control I²C devices from your computer. All samples programs can be downloaded from the 'Attachments/Downloads' section on this page.

Robotertechnik ist in den letzten Jahren zunehmend in den Blick der Öffentlichkeit geraten. Nicht zuletzt aufgrund der immer häufiger werdenden Anwendungen im industriellen Bereich, im Spielzeugsektor und auch im Haushalt. Robotertechnik als Hobby ist besonders interessant und stellt eine außergewöhnliche Herausforderung dar, da dieses Hobby Fachgebiete wie Elektronik, Mechanik und Informatik verbindet. Es fördert daher in hohem Masse die Fähigkeit, vernetzt zu denken und komplexe, voneinander abhängige Sachverhalte zu erkennen. Roboter-Wettbewerbe – wie zum Beispiel die alljährlich ausgetragene Roboter-Fußball-Weltmeisterschaft – sind ein besonderes Highlight, übersteigen allerdings in den meisten Fällen die Möglichkeiten eines Hobbyisten bei weitem. Andererseits ist der Aufbau eines vorgefertigten Bausatzes oder gar der Betrieb eines fertigen Roboters keine echte Herausforderung und wird schnell langweilig, zumal diese Roboter in der Regel auch keine realen Aufgaben erfüllen können. Besonders beeindruckend ist es, wenn ein Roboter sich nicht nur mehr oder weniger geschickt umher bewegt, sondern dabei gleichzeitig noch das Zimmer reinigt. Dieses Buch stellt verschiedenste Möglichkeiten zum Selbstbau von Reinigungsrobotern vor; angefangen von einfachen mechanisch gesteuerten Wischrobotern bis hin zu komplexen, mikroprozessorgesteuerten Saugrobotern mit diversen Varianten der Hinderniserkennung. Dabei legt der Autor besonderen Wert auf die einfache und preiswerte Herstellung funktioneller Roboter.

32 new Projects, Practical Examples and Exercises with the Elektor Arduino Nano MCCAB Training Board Electronics and microcontroller technology offer the opportunity to be creative. This practical microcontroller course provides you with the chance to bring your own Arduino projects and experience such moments of success. Ideally, everything works as you imagined when you switch it on for the first time. In practice, however, things rarely work as expected. At that point, you need knowledge to efficiently search for and find the reason for the malfunction. In this book for advanced users, we delve deep into the world of microcontrollers and the Arduino IDE to learn new procedures and details, enabling you to successfully tackle and solve even more challenging situations. With this book, the author gives the reader the necessary tools to create projects independently and also to be able to find errors quickly. Instead of just offering ready-made solutions, he explains the background, the hardware used, and any tools required. He sets tasks in which the reader contributes their own creativity and writes the Arduino sketch themselves. If you don’t have a good idea and get stuck, there is, of course, a suggested solution for every project and every task, along with the corresponding software, which is commented on and explained in detail in the book. This practical course will teach you more about the inner workings of the Arduino Nano and its microcontroller. You will get to know hardware modules that you can use to realize new and interesting projects. You will familiarize yourself with software methods such as ‘state machines,’ which can often be used to solve problems more easily and clearly. The numerous practical projects and exercise sketches are once again realized on the Arduino Nano MCCAB Training Board, which you may already be familiar with from the course book ‘Microcontrollers Hands-on Course for Arduino Starters’, and which contains all the hardware peripherals and operating elements we need for the input/output operations of our sketches. Readers who do not yet own the Arduino Nano MCCAB Training Board can purchase the required hardware separately, or alternatively, build it on a breadboard.
