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!
Temporary Delay in the Delivery of Unitree Robots
Like many other suppliers, we are currently experiencing delays in the delivery of Unitree robots. A shipment from our supplier is currently held in customs, which has unfortunately led to later-than-planned deliveries for previously placed orders. We are actively working with our supplier to resolve this issue and expect more clarity soon, but at this time, we cannot provide any guarantees.
Additionally, a new shipment is already on its way, though it will take some time to arrive. Since other suppliers are facing similar challenges, switching to a different provider is unlikely to result in a faster solution. Our top priority remains fulfilling existing orders.
If you have any questions or would like to update your order, please do not hesitate to contact our customer service team. We will keep you informed of any further developments.

Mastering the Language and the Development Platform
Many people would like to learn Java but getting started is not easy since programming with Java requires at least two things: mastering the programming language and the development environment. With the help of many examples, this book shows how the language is structured. In addition, it employs the Eclipse development environment as an example of a powerful tool to teach developing Java programs.
In Basics, the first part of the book, you acquire your Java and Eclipse basic knowledge. This part lays the programming foundations, gives you an overview of Java technology, and shows you what is special about object-oriented programming.
In the second part called Java Language, everything revolves around the subtleties of the Java language and this is where the first small Java applications are created, aided by a fine blend of the knowledge part and practical exercises.
Java Technology is both the name and the focus of the third part which also introduces you to the rules to observe when programming, what class libraries are and what advantages they have. In addition, you will learn how to test programs, what algorithms are, and how to program them.
The fourth part, Java Projects, enables you to apply all the previous elements in an application with a graphical user interface. The project shows how to develop a larger application piece by piece with the Eclipse development environment. The Appendix concludes with a section on frequent errors that can occur when working with Eclipse, and a Glossary.
With this 65 W USB-C PD power supply (with GaN technology) you can start using the FNIRSI HS-01 soldering iron straight away. Of course, you can also use this charger to fast charge your tablets and smartphones via USB-C and USB-A.

If you enjoy DIY electronics, projects, software and robots, you’ll find this book intellectually stimulating and immediately useful. With the right parts and a little guidance, you can build robot systems that suit your needs more than overpriced commercial systems can.
20 years ago, robots based on simple 8-bit processors and touch sensors were the norm. Now, it’s possible to build multi-core robots that can react to their surroundings with intelligence. Today’s robots combine sensor readings from accelerometers, gyroscopes and computer vision sensors to learn about their environments. They can respond using sophisticated control algorithms and they can process data both locally and in the cloud.
This book, which covers the theory and best practices associated with advanced robot technologies, was written to help roboticists, whether amateur hobbyist or professional, take their designs to the next level. As will be seen, building advanced applications does not require extremely costly robot technology. All that is needed is simply the knowledge of which technologies are out there and how best to use each of them.
Each chapter in this book will introduce one of these different technologies and discuss how best to use it in a robotics application. On the hardware side, we’ll cover microcontrollers, servos, and sensors, hopefully inspiring you to design your own awe-inspiring, next-generation systems. On the software side, we’ll cover programming languages, debugging, algorithms, and state machines. We’ll focus on the Arduino, the Parallax Propeller, Revolution Education PICAXE and projects I’ve with which I’ve been involved, including the TBot educational robot, the PropScope oscilloscope, the 12Blocks visual programming language, and the ViewPort development environment. In addition, we’ll serve up a comprehensive introduction to a variety of essential topics, including output (e.g. LEDs, servo motors), and communication technologies (e.g. infrared, audio), that you can use to develop systems that interact to stimuli and communicate with humans and other robots. To make these topics as accessible as possible, handy schematics, sample code and practical tips regarding building and debugging have been included.

De werking van veruit de meeste moderne elektronische apparaten is niet slechts op één enkel principe gebaseerd. Vaak staat een of andere computer (doorgaans een microcontroller) centraal. Uit deze fundamentele opzet – een computer die is ingebed in een bepaalde toepassingsschakeling – is de algemene benaming Embedded Systems voortgekomen. De meeste van deze systemen moeten vanuit het niets worden ontwikkeld, en daarbij komt het op elk detail aan. Vindingrijkheid en veelzijdigheid zijn dan een vereiste. De problemen die opgelost moeten worden, vormen niet zelden een ware uitdaging en betreffen niet alleen de analoge en digitale elektronica maar ook de systeemarchitectuur, programmering en programma-organisatie.
De delen van deze reeks zijn geschreven voor iedereen – leerling, student of beginnend elektronicus – die zich terdege wil bekwamen in de professionele hardware- en systeemontwikkeling. En ze richten zich tot de allround-elektronicus die geen tijd heeft om specialist op een van de vele deelgebieden te worden maar die weet dat hij met standaard huis-, tuin- en keukenoplossingen niet ver komt. Ze bieden wat studenten en professionele elektronici nodig hebben: een opfrissing en verdieping van de basiskennis, een bron van inspiratie en een schat aan details en spitsvondigheden.
Dit deel behandelt de passieve componenten:
vaste weerstanden
instelbare weerstanden
NTC- en PTC-weerstanden
spanningsafhankelijke weerstanden
condensatoren
spoelen
transformatoren
contactelementen

Daran schließt sich die Beschreibung des elektrischen und magnetischen Feldes an.
Zur Erzielung einer optimalen Verständlichkeit erfolgt die Darbietung des Stoffes nach dem Grundsatz, den Leser von einfachen Sachverhalten schrittweise zu komplexeren Problemstellungen zu führen. Zusätzlich sind den einzelnen Abschnitten Aufgaben mit ausführlichen Lösungswegen zugeordnet. Sie sind zum Erfassen der Gedankengänge von besonderer Bedeutung. Das Buch ist in acht Kapiteln unterteilt:
Physikalische Größen und ihre Einheiten
Elektrotechnische Größen im Gleichstromkreis
Einfacher Stromkreis
Erweiterter Strombereich
Messgeräte für die Grundschaltungen der Elektronik
Kondensator
Spulen, Transformatoren, Relais und Lautsprecher
Zusammengesetzte Wechselstromkreise
Die Aufgaben sind zum großen Teil der elektrotechnischen Praxis entnommen und werden mit steigendem Schwierigkeitsgrad angeboten, so dass für jede Vorbildungsstufe geeigneter Übungsstoff zu finden ist. Der Inhalt ist als Hilfsmittel für den Unterricht und das Selbststudium bestimmt, sie kann auch dem Praktiker beim Auffrischen seiner Kenntnisse und zur Förderung seiner Rechenfertigkeit nützlich sein.
Mit diesem Buch gibt der Autor sein gesamtes Wissen, das er sich im Laufe der Zeit in der Industrie und dem Unterricht an einer Technikerschule angeeignet hat, an den Leser weiter.
