Projects Using Arduino IDE and the LVGL Graphics Library
The ESP32 is probably one of the most popular microcontrollers used by many people, including students, hobbyists, and professional engineers. Its low cost, coupled with rich features makes it a popular device to use in many projects. Recently, a board called the ESP32 Cheap Yellow Display (CYD for short) is available from its manufacturers. The board includes a standard ESP32 microcontroller together with a 320x240 pixel TFT display. Additionally, the board provides several connectors for interfaces such as GPIO, serial port (TX/RX), power and Ground. The inclusion of a TFT display is a real advantage as it enables users to design complex graphics-based projects without resorting to an external LCD or graphics displays.
The book describes the basic hardware of the ESP32 CYD board and provides details of its on-board connectors. Many basic, simple, and intermediate-level projects are given in the book based on the ESP32 CYD, using the highly popular Arduino IDE 2.0 integrated development environment. The use of both the basic graphics functions and the use of the popular LVGL graphics library are discussed in the book and projects are given that use both types of approaches.
All the projects given in the book have been tested and are working. The block diagram, circuit diagram, and the complete program listings and program descriptions of all the projects are given with explanations. Readers can use the LVGL graphics library to design highly popular eye-catching full-color graphics projects using widgets such as buttons, labels, calendars, keypads, keyboards, message boxes, spinboxes, sliders, charts, tables, menus, bars, switches, drop-down lists, animations, and many more widgets.

From Rubbing Amber to Swiping Glass
"The story of electricity, told one connection at a time."Why does rubbing amber attract dust? How did we go from that curious effect to a world where screens respond to a single touch? And how did we get from mysterious sparks to tiny chips packed with billions of transistors?
For centuries, electricity puzzled and fascinated those who encountered its curious effects—long before it even had a name. From the earliest observations of static charge to the complex electronics that shape our lives today, this book traces the gradual, and often surprising, story of how humanity came to understand and harness this powerful force.
This book offers an engaging and accessible account of the people, ideas, and inventions that transformed electricity from a scientific curiosity into the foundation of our digital age. Along the way, you’ll meet a host of inquisitive minds—some famous, others less so—whose persistence and creativity helped unravel the mysteries of the natural world and gave rise to the technologies we now take for granted.
Covering everything from Leyden jars and batteries to transistors, microcontrollers and the internet, this book presents a clear and enjoyable overview of electronics and its relatively short, yet rich, history.
Whether you have a technical background or simply a curiosity about how things work, From Rubbing Amber to Swiping Glass offers a thoughtful look at how far we’ve come—and a gentle nudge to wonder what might come next.
Understanding and Using Them Effectively
What happens in electronics is invisible to the naked eye. The instrument that allows to accurately visualize electrical signals, the one through which the effects of electronics become apparent to us, is the oscilloscope.
Alas, when one first ventures into electronics, it is often without an oscilloscope. And one is left fumbling, both physically and mentally. Observing an electrical signal on a screen for the first time is a revelation. Nobody wishes to forgo that marvel again. There is no turning back.
In electronics, if one wishes to progress with both enjoyment and understanding, an oscilloscope is essential. This marks the beginning of a period of questioning: how to choose one? And no sooner is that question answered than a whole string of others arises, which can be summed up in just one: how does one use the oscilloscope in such a way that what it displays truly reflects the reality of the signals?
Rémy Mallard is a passionate communicator with a gift for making complex technical subjects understandable and engaging. In this book, he provides clear answers to essential questions about using an oscilloscope and offers a wealth of guidance to help readers explore and understand the electrical signals behind electronic systems. With his accessible style and practical insights, this book is a valuable tool for anyone eager to deepen their understanding of electronics.
Eine Einführung in die Schaltungssimulation
LTspice wurde von Mike Engelhardt entwickelt und gehört inzwischen zu Analog Devices. Es handelt sich dabei um ein Programm zur Schaltplanerstellung – einen leistungsstarken, schnellen und kostenlosen SPICE-Simulator sowie um ein Werkzeug zur Darstellung von Kurvenverläufen. Es bietet eine umfangreiche Bauteildatenbank, die weltweit durch SPICE-Modelle unterstützt wird.
Mit LTspice kann man schnell und einfach Schaltpläne erstellen. Dank der leistungsfähigen grafischen Ausgabefunktionen lassen sich Spannungen und Ströme in einer Schaltung, die Leistungsaufnahme der Bauteile und viele weitere Parameter darstellen.
Ziel dieses Buches ist es, den Entwurf und die Simulation elektronischer Schaltungen mit LTspice zu vermitteln. Es behandelt unter anderem folgende Themen:
DC und AC-Schaltungen
Kleinsignal- und Z-Dioden
Transistorschaltungen inkl. Oszillatoren
Tryristor-, Diac- und Triacschaltungen
Operationsverstärkerschaltungen inkl. Oszillatoren
Der 555 Timer-IC
Filter
Spannungsregler
Optokoppler
Erstellung von Spannungskurven
Simulation von Logikschaltungen mit der 74HC-Familie
SPICE-Modellierung
LTspice ist ein äußerst vielseitiges Werkzeug zur Simulation elektronischer Schaltungen mit zahlreichen Funktionen und Anwendungsmöglichkeiten. Eine vollständige Behandlung aller Details würde jedoch den Rahmen dieses Buches sprengen. Daher konzentriert sich das Buch auf die gängigsten Themen wie DC- und AC-Analyse, Parametersweep, Übertragungsfunktionen, Oszillatoren, Diagramme und weitere grundlegende Anwendungen.
Obwohl es sich um eine Einführung handelt, deckt dieses Buch dennoch die meisten Interessensgebiete all jener ab, die sich mit der Simulation elektronischer Schaltungen beschäftigen.
Resonances From Aether Days
A Pictorial and Technical Analysis from WWII to the Internet Age
From the birth of radio to the late 1980s, much of real life unfolded through shortwave communication. World War II demonstrated—beyond a shadow of a doubt—that effective communications equipment was a vital prerequisite for military success. In the postwar years, shortwave became the backbone on which many of the world's most critical services depended every day.
All the radio equipment—through whose cathodes, grids, plates, and transistors so much of human history has flowed—is an exceptional subject of study and enjoyment for those of us who are passionate about vintage electronics. In this book, which begins in the aftermath of World War II, you’ll find a rich collection of information: descriptions, tips, technical notes, photos, and schematics that will be valuable for anyone interested in restoring—or simply learning about—these extraordinary witnesses to one of the most remarkable eras in technological history.
My hope is that these pages will help preserve this vast treasure of knowledge, innovation, and history—a heritage that far transcends the purely technical.

Praktischer Einstieg mit Arduino, GnuRadio und FPGA
Das Thema „Software Defined Radio“ ist facettenreich: Neben der Schaltungstechnik ist auch eine Einarbeitung in die Programmierung von Hardware und PC wichtig. Ein schrittweises Vorgehen erleichtert Ihnen den Einstieg. Mit dem im Buch vorgestellten modularen „RF Bricks“-Konzept werden Sie zum Architekten Ihrer Signalkette. Auf einem Chassis angeordnet gewährleisten die Module einen soliden und gut abgeschirmten Aufbau, den Sie einfach verändern und mit eigenen Ideen anreichern können.
Der skalierbare Aufbau bildet Ihr Blockschaltbild auch mechanisch ab – die so gewonnene Übersicht kann in der Aus- und Weiterbildung nützlich sein. Ein Arduino in Ihrem Chassis kommuniziert nach einigen Anpassungen mit üblichen SDR-Programmen, z. B. SDRCPP, GQRX und CubicSDR auf einer Linux-Plattform. Damit können Sie Ihren Empfänger direkt per Mausklick abstimmen.
Wenn Sie Blockschaltbilder mögen, ist GnuRadio ein natürlicher Partner der „RF Bricks“. Mit einem selbst programmierten Python-Block gelingt Ihnen in GnuRadio die Fernsteuerung Ihres Empfängers. Im GnuRadio-Universum können Sie Ihre GUI stufenweise ausbauen, behalten dabei aber immer volle Kontrolle über die inneren Abläufe des Programms.
Mit einem FPGA können zeitaufwändige Operationen auch direkt in die Hardware verlagert werden. Sie bauen stufenweise einen Doppelsuperhet auf und entwickeln die Filterkoeffizienten für FIR-Filter mit Scilab. Das in VHDL realisierte Weaver-Schema rundet diesen Empfänger ab, der mit hoher Empfindlichkeit und Dynamik aufwarten kann.
Mit dem gewonnen Überblick und Ihrer neuen Hardware können Sie die einzelnen Aspekte des Themenkomplexes SDR beliebig weiter vertiefen.

A Combat Guide against E-waste and Throwawayism
This book is for anyone who enjoys tinkering with analog and digital hardware electronics. Regardless of the sophistication of your workspace, only basic tools are required to achieve truly satisfying results. It is intended as a reference guide among other hardware repair publications you may have in your library. However, the book goes a step further than most other repair guides in addressing issues in the modern era of discarded electronics called e-waste.
E-waste should be put to good use. Producing anything new requires not just precious resources and labor, but also energy to make and deliver it to global retail shelves. Your talents and love of electronics can be put to good use by rescuing and resurrecting at least selected units from this endless stream of e-waste. Examples include either restoring through repair, or salvaging reusable electronic and mechanical components for your next project.
Smart tips are provided throughout the book, and much information is tabulated for easy reference. The book expands age-old repair and hacking techniques applied for repair on the workbench into clever methods and applications to achieve effective results with discarded or “non-servicable” electronic consumer products. The final chapter provides real-life examples using all of the previously discussed content in a summarized form for each example repair type.
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.
