Mikrocontroller wie der Arduino und Einplatinenrechner wie der Raspberry Pi haben sich zu beliebten Komponenten entwickelt. Dritter im Bunde ist der ESP32 der Firma Espressif. Mikrocontroller dieser Baureihe zeichnen sich durch eine Vielzahl implementierter Funktionen aus, die bei einem Arduino konventioneller Pragung mit einem Atmel-AVR-Mikrocontroller erst mit weiterer Hardware moglich sind. Prominentes Beispiel sind hier die WiFi- und Bluetooth-Funktionalitaten. Gegenuber einem Raspberry Pi zeichnen sie sich durch einen deutlich geringeren Preis aus. Allgemeine Informationen fur die Realisierung eines Roboterauto-Projekts mit dem ESP32 sind leicht zu finden. Dabei handelt es sich aber oft nur um Ausfuhrungen zu einem Teilaspekt, ohne inhaltliche oder funktionale Abstimmung. So ist nicht nur die Beschaffung der benotigten Informationen muhselig und zeitaufwandig, sie kann auch au?erordentlich fehlertrachtig sein.

Affordable solutions with the ESP8266 and 3D printing. If you are looking for a small yet powerful IoT device, you are likely to come across the ESP8266 and compatible products on the market today. One of these, the Wemos/Lolin D1 Mini Pro board strikes a remarkable balance between cost and performance. A small and very affordable prototype board, the D1 Mini Pro stands out with its WiFi functionality and a 16-Mbytes flash memory for easy creation of a flash file system. In addition, there are sufficient input and output pins (only one analog input though) to support PWM, I?C, and One-Wire systems to mention but a few. The book describes the operation, modding, construction, and programming of home appliances including a colorful smart home accessory, a refrigerator/greenhouse controller, an AC powerline monitor, a door lock monitor, and an IKEA Tradfri controller. As a benefit, all firmware developed for these DIY, "IoT-ized" devices can be updated over-the-air (OTA). For most of the designs in the book, a small printed circuit board (PCB) and an enclosure are presented so readers can have a finished and attractive-looking product. Readers having or with access to! a 3D printer can "print" the suggested enclosures at home or in a shop.

There is a new edition of this book: Programming The Raspberry Pi Pico/W In C, Second Edition. The Raspberry Pi Pico is a remarkable microcontroller. It has a power and sophistication that would have been unthinkable just a short time ago. For the sort of jobs it is ideal for, it has plenty of processing power and enough memory to make tasks that would have once required careful planning, relatively easy. Instead of struggling with the machine, you can now focus on getting a good implementation of your algorithms. To enjoy all of its power and sophistication there is no better language than C. It wastes none of the power and it gives you what you need to get at the new features. However, getting started with the Pico with C is no easy feat, which is what motivated this book about creating programs so that testing and debugging is easy. Programming the Raspberry Pi Pico in C uses the highly popular VS Code as its development environment and shows how to use a Raspberry Pi or a desktop PC running Windows as your development machine. The purpose of the book is to reveal what you can do with the Pico's GPIO lines together with widely used sensors, servos and motors and ADCs. After covering the GPIO, outputs and inputs, events and interrupts, it gives you hands-on experience of PWM (Pulse Width Modulation), the SPI bus, the I2C bus and the 1-Wire bus.

Plot, Cut, Drill, Mill and Laser with the Z99. This book covers the construction, hardware, software, and operation of the Z99 CNC machine. This is a multifunctional 4-axis machine for home construction. By making the support software available as freeware, readers of the book are challenged and encouraged to develop new applications for the Z99. The machine would not be of much use if the user has no option to create suitable files for the designs in mind. A large part of this book is dedicated to creating source files in a variety of freeware software packages, including Inkscape, DesignSpark PCB, KiCad, and FlatCAM. The book is also useful for readers keen to comprehend and then master the basic structure of HPGL, Gerber, Drill, and G-code files, as well as to have a go at deciphering them using software.

The Arduino Uno is an open-source microcontroller development system encompassing hardware, an Integrated Development Environment (IDE), and a vast number of libraries. It is supported by an enormous community of programmers, electronic engineers, enthusiasts, and academics. The libraries in particular really smooth Arduino programming and reduce programming time. Whats more, the libraries greatly facilitate testing your programs since most come fully tested and working. The Raspberry Pi 4 can be used in many applications such as audio and video media devices. It also works in industrial controllers, robotics, games, and in many domestic and commercial applications. The Raspberry Pi 4 also offers Wi-Fi and Bluetooth capability which makes it great for remote and Internet-based control and monitoring applications.

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, theres 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.

Most people think it is convenient to walk simply into a store selling computers that are branded and buy one. Everyone has to get a new computer at some time or another so why not get the computer you always wanted? Sure you can buy a nice computer off of the store shelf but you never really get exactly what you want that way. When you build your own computer, you are in charge of what components are going to be used so you know that it will perform the way you want it to. The goal of this book is to help you choose the parts (components) for your new computer so you can end up with a computer that does what you want it to do. Then you will be taken through the build process with step by step instructions and illustrations making it easy to get your new computer up and running in no time. Finally you will be guided through the process of installing an operating system on your computer so you can start enjoying your work.

One-dimensional semiconducting materials are expected to produce highly-efficient electronic components due to their extraordinary characteristics in applications like nanoscale electronics, biology, optoelectronics, and energy storage. Moreover, complex semiconducting materials have also been developed from nanowires using epitaxial growth mechanisms. The current application areas of nanowires include high-speed transistors, nanoelectronics, chemical- and biosensors, and LEDs (light-emitting diodes) with little power consumption. Concerns for the synthesis of these devices include inferior mobility and optical characteristics of nanomaterials materials. This book offers a thorough understanding of recent developments in synthesizing nanowires for constructing various types of electronic components. Especially, the book reviews the uses of nanowires in sensors, detectors, energy storage, circuits, and energy conversion, etc. Growth approaches of various types of nanowires are also discoursed along with the discussion of their electronic applications. Therefore, this book can be used as a ready reference by researchers, students, and teachers in the field of nanotechnology and electronics.
