The Elektor Audio DSP FX Processor combines an ESP32 microcontroller and an ADAU1701 Audio DSP from Analog Devices. Besides a user-programmable DSP core, the ADAU1701 has high-quality analog-to-digital and digital-to-analog converters built-in and features an I²S port. This makes it suitable as a high-quality audio interface for the ESP32. Programs for the ESP32 can be created with Arduino, Platform IO, CMake or by using the Espressif IDF in another way. Programs for the ADAU7101 audio DSPs are created with the free visual programming tool SigmaStudio by dragging and dropping pre-defined algorithm blocks on a canvas.

Clever Tricks with ATmega328 Pro Mini Boards With a simple Pro Mini board and a few other components, projects that 20 or 30 years ago were unthinkable (or would have cost a small fortune) are realized easily and affordably in this book: From simple LED effects to a full battery charging and testing station that will put a rechargeable through its paces, there’s something for everyone. All the projects are based on the ATmega328 microcontroller, which offers endless measuring, switching, and control options with its 20 input and output lines. For example, with a 7-segment display and a few resistors, you can build a voltmeter or an NTC-based thermometer. The Arduino platform offers the perfect development environment for programming this range of boards. Besides these very practical projects, the book also provides the necessary knowledge for you to create projects based on your own ideas. How to measure, and what? Which transistor is suitable for switching a certain load? When is it better to use an IC? How do you switch mains voltage? Even LilyPad-based battery-operated projects are discussed in detail, as well as many different motors, from simple DC motors to stepper motors. Sensors are another exciting topic: For example, a simple infrared receiver that can give disused remote controls a new lease on life controlling your home, and a tiny component that can actually measure the difference in air pressure between floor and table height!

A Project-Based Introduction to Microcontrollers and Drone Control A Practical Introduction to Embedded Systems with the ESP32 This book is intended for readers who are new to embedded systems and looking for a structured, example-driven way to begin. If you’ve explored general-purpose electronics or Arduino-based resources but found them too broad or lacking in practical application, this guide offers a more focused alternative. With a small, affordable set of components – such as LEDs, sensors, an OLED screen and a motion sensor – you’ll build and work with the same hardware setup throughout the book. This allows you to focus on learning and experimenting without constant reconfiguration. Topics include: Understanding and programming the ESP32 microcontroller Using the Arduino IDE to write and deploy code Exploring cyber-physical systems, culminating in basic drone control No prior experience with Arduino or embedded development is required. Each section includes hands-on examples and mini-projects designed to reinforce core concepts and encourage deeper exploration. By the end, you’ll be equipped not only to reproduce the book’s examples, but also to extend them toward your own ideas and applications. Whether your interest is in learning embedded programming, building interactive systems, or exploring educational drone control, this book provides a clear and practical path to getting started.

Physical Computing met het Arduino-platform Dit leerboek over het Arduino-platform is uniek en brengt u stap voor stap van beginner tot gevorderde Arduino-gebruiker. Er wordt duidelijk in uitgelegd waarom en waardoor toepassingen werken, ondersteund door gedetailleerde afbeeldingen in kleur. Er is slechts een geringe elektronische basiskennis vereist, omdat de benodigde hardware uitgebreid wordt besproken. Het laatste gedeelte van dit boek bevat een degelijke theoretische verdieping, zodat u een krachtig naslagwerk achter de hand houdt. Er bestond in het Nederlands nog geen lesboek over dit platform. De didactische opbouw is zodanig dat de vereiste abstracte kennis wordt uitgelegd aan de hand van toepasbare en actuele praktijkvoorbeelden. De meeste toepassingen zijn gericht op ‘physical computing’, dat is de interactie tussen sensoren, actoren, elektronica en software. Hierdoor is het boek ook geschikt voor technisch beroepsonderwijs, o.a. voor de richting mechatronica. De opbouw van het boek is als volgt: Algemene introductie microcontrollers. Informatie over het Arduino-platform. Oefeningen met uitleg aan de hand van 21 voorbeelden. Praktijkvoorbeelden met uitleg aan de hand van 5 voorbeelden. Theoretische verdieping van de software en hardware. Praktische elektronicaschema´s. Alle software-voorbeelden in het boek zijn als download beschikbaar.
