Vom Messwert zur stabilen Entscheidung Wie wird aus einem einfachen Mikrocontroller ein intelligentes System, das Sensorwerte erfasst, verarbeitet und sinnvoll darauf reagiert? Dieses Buch zeigt es Ihnen Schritt für Schritt – verständlich, praxisnah und ohne unnötige Vorkenntnisse. Sie beginnen mit den Grundlagen der digitalen und analogen Ein- und Ausgänge. Anschließend lernen Sie, wie Sensorwerte gelesen, geglättet und zuverlässig bewertet werden. Anschauliche Beispiele erklären, warum einzelne Messwerte oft täuschen können und wie Mittelwertbildung, Hysterese und einfache Entscheidungsregeln für stabile Ergebnisse sorgen. Nach und nach erweitern Sie Ihre Projekte um Displays, I²C-Kommunikation und mehrere vernetzte Mikrocontroller. So entstehen verteilte Systeme, in denen Raspberry Pi Pico und ATtiny-Controller Daten austauschen und gemeinsam Aufgaben übernehmen. Im fortgeschrittenen Teil erhalten Sie einen leicht verständlichen Einstieg in Merkmalsbildung, Datenvorverarbeitung, hybride Entscheidungsmodelle und TinyML-nahe Anwendungen. Dabei verbinden Sie klassische Regelungstechnik mit modernen datenbasierten Methoden. Alle Projekte werden von ausführlich kommentierten Programmen in C und MicroPython begleitet. Das Buch richtet sich an Einsteiger, Maker, Studierende und alle, die Embedded-Systeme von Grund auf verstehen möchten. Am Ende können Sie eigene Systeme entwickeln, die nicht nur messen, sondern Informationen auswerten, zuverlässige Entscheidungen treffen und gezielt reagieren.

With Examples for Arduino UNO, Raspberry Pi Pico and ESP32 Programming small electronic systems has never been more accessible. Tasks that once demanded expensive tools, specialized hardware, and deep electrical engineering expertise can now be tackled with low-cost development boards and approachable software. At the centre of this shift is the Arduino environment, which provides a unified and familiar way to program a wide range of microcontroller platforms—from classic AVR boards like the Arduino UNO to modern ARM-based boards such as the Raspberry Pi Pico, and powerful Wi-Fi-enabled devices like the ESP32. This book introduces embedded programming through the core idea that defines all microcontrollers: reading inputs, processing information, and controlling outputs in a predictable loop. The Arduino environment abstracts much of the hardware complexity, allowing you to focus on behaviour rather than implementation details. With just a few lines of code, you can blink LEDs, read sensors, control motors, and communicate with other devices. While the Arduino UNO, Raspberry Pi Pico, and ESP32 boards differ greatly in performance and features, they share the same fundamental building blocks: digital and analog I/O, timers, serial communication, PWM, interrupts, and power management. Learning these concepts within the Arduino framework builds skills that transfer easily across platforms and scale toward more advanced applications. By exploring multiple boards while maintaining a consistent programming approach, this book helps you progress from simple experiments to confidently produce well-structured designs—showing that embedded development can be both practical and enjoyable.

The first chapters describe the process of Alexa communication, opening an Amazon account and creating a skill for free. The operation of an Alexa skill and terminology such as utterances, intents, slots, and conversations are explained. Debugging your code, saving user data between sessions, S3 data storage and Dynamo DB database are discussed. In-skill purchasing, enabling users to buy items for your skill as well as certification and publication is outlined. Creating skills using AWS Lambda and ASK CLI is covered, along with the Visual Studio code editor and local debugging. Also covered is the process of designing skills for visual displays and interactive touch designs using Alexa Presentation Language. The second half of the book starts by creating a Raspberry Pi IoT 'thing' to control a robot from your Alexa device. This covers security issues and methods of sending and receiving MQTT messages between an Alexa device and the Raspberry Pi. Creating a smart home device is described including forming a security profile, linking with Amazon, and writing a Lambda function that gets triggered by an Alexa skill. Device discovery and on/off control is demonstrated. Next, readers discover how to control a smart home Raspberry Pi display from an Alexa skill using Simple Queue Service (SQS) messaging to switch the display on and off or change the color. A node-RED design is discussed from the basic user interface right up to configuring MQTT nodes. MQTT messages sent from a user are displayed on a Raspberry Pi. A chapter discusses sending a proactive notification such as a weather alert from a Raspberry Pi to an Alexa device.
