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.

Learn to interface and program hardware devices in a wide range of useful applications, using ARM7 microcontrollers and the C programming language. Examples covered in full detail include a simple LED to a multi-megabyte SD card running the FAT file system. Features of this book Build prototype circuits on breadboard or Veroboard and interface to ARM microcontrollers. A 32-bit ARM7 microcontroller is used in interfacing and software examples. Interfacing principles apply to other ARM microcontrollers and other non-ARM microcontrollers as well. Example programs are written in the C programming language. Use only free or open source software. Download and install all programming tools from the Internet. Template project files are provided for easy project creation. Hardware Interface to LEDs, transistors, optocouplers, relays, solenoids, switches, keypads, LCD displays, seven segment displays, DC motors, stepper motors, external analogue signals using the ADC, RS232, RS-485, TWI, USB, SPI and SD memory cards. Software Once hardware has been interfaced to a microcontroller, software must be written to control the hardware. You will learn how to write programs to operate externally interfaced hardware devices, use timers and interrupts. Also learn how to port FAT file system code for use with an SD memory card, program the PWM to produce an audio sine wave, program the PWM to speed control a DC motor and more. A chapter on more advanced ARM microcontrollers is included with an overview of some of the newest ARM microcontrollers and their features.

Die Messung der leitungsgebundenen Emission ist die einfachste und kostengünstigste Methode, um einen Hinweis darauf zu erhalten, ob ein Design die EMI/EMV-Anforderungen erfüllen kann. Ein Line Impedance Stabilization Network (LISN) ist dabei ein unverzichtbarer Bestandteil eines EMV-Prüfaufbaus (Pre-Compliance). In Zusammenarbeit mit Würth Elektronik hat Elektor einen 5 µH, 50 Ω Dual DC LISN entwickelt, der Spannungen bis zu 60 V und Ströme bis zu 10 A unterstützt. Das Gerät misst HF-Störungen auf beiden Kanälen (der Stromversorgung) mit Hilfe von 5-μH-Sperrinduktivitäten. Das interne 10-dB-Dämpfungsnetzwerk – eines in jedem Kanal – enthält einen Hochpassfilter dritter Ordnung mit einer Grenzfrequenz von 9 kHz, um den Eingang von Instrumenten wie z. B. einem Spektrumanalysator vor potenziell schädlichen Gleichspannungen oder niedrigen Frequenzen zu schützen, die vom Prüfling (EUT – Equipment Under Test) stammen.

This is the second edition of a book aimed at engineers, scientists, and hobbyists who want to interface PCs with hardware projects using graphical user interfaces. Desktop and web-based applications are covered. The programming language used is Python 3, which is one of the most popular languages around: speed of programming being a key feature. The book has been revised and updated with an emphasis on getting the user to produce practical designs with ease – a text editor is all that is required to produce Python programs. Hardware interfacing is achieved using an Arduino Uno as a remote slave. A full description and source code of the communication interface is given in the book. The slave provides digital and analog input and outputs. Multiple Unos can be included in one project with all control code written in Python and running on a PC One project involves a PIC microcontroller with the code provided that can be loaded into the PIC using the Uno. The web applications and server are all implemented in Python, allowing you to access your electronic hardware over the Internet. The Raspberry Pi computer can be used as your web server. An introductory chapter is provided to get you started with using Linux. The book is written for use with Debian or variations including Mint or Ubuntu. All of the programs in the book are freely available, ready to use and experiment with by way of a download from Elektor.

EAGLE – the “Easily Applicable Graphical Layout Editor“ is a professional-grade CAD (computer aided design) software package for the design and drafting of electronic schematics as well as the design and fabrication of printed circuit boards (PCBs). This Advanced User Guide provides the experienced EAGLE user with insight into using some of the more advanced features of EAGLE software. It is not a guide to teach the reader the basic concepts of EAGLE, nor does it discuss the ‘how to’ of the EAGLE interface and the simpler operations and commands of the software. That is the purpose of the author’s previous title EAGLE V6 Getting Started Guide also published by Elektor. This eBook is intended as an enduring document covering the more advanced modules, commands, and functions which make up EAGLE. It is hoped that this eBook will provide a quick, succinct reference to assist with more complex applications and uses of EAGLE – an ‘EAGLE User’s Companion’, if you like. Complementing the EAGLE Advanced User Guide, the EAGLE User Language manual is included in this eBook in unabridged form, reproduced with permission of CadSoft GmbH. At the time of writing, the material in this eBook covers version 7 of the EAGLE software suite.

A Small Basic Approach There are many different PC programming languages available on the market. Some have beautiful names; some have easy to use development tools. Others have incredible power. They all have one thing in common: they assume that you have, or want to have, a knack for technology and difficult to read commands. In this book we take a practical approach to programming. We assume that you simply want to write a PC program, and write it quickly. Not in a professional environment, not in order to start a new career, but for plain and simple fun... or just to get a task done. Therefore we use Small Basic. You will have an application up and running in a matter of minutes. You will understand exactly how it works and be able to write text programs, graphical user interfaces, and advanced drivers. It is so simple; you don't even need to be an adult!
