Using the RFID Starter Kit An Arduino board has now become ‘the’ basic component in the maker community. No longer is an introduction to the world of microcontrollers the preserve of the expert. When it comes to expanding the capabilities of the basic Arduino board however, the developer is still largely on his own. If you really want to build some innovative projects it’s often necessary to get down to component level. This can present many beginners with major problems. That is exactly where this book begins. This book explains how a wide variety of practical projects can be built using items supplied in a single kit together with the Arduino board. This kit, called the 'RFID Starter Kit for Arduino' (SKU 17240) is not just limited to RFID applications but contains more than 30 components, devices and modules covering all areas of modern electronics. In addition to more simple components such as LEDs and resistors there are also complex and sophisticated modules that employ the latest technology such as: A humidity sensor A multicolor LED A large LED matrix with 64 points of light A 4-character 7-segment LED display An infra red remote-controller unit A complete LC-display module A servo A stepper motor and controller module A complete RFID reader module and security tag On top of that you will get to build precise digital thermometers, hygrometers, exposure meters and various alarm systems. There are also practical devices and applications such as a fully automatic rain sensor, a sound-controlled remote control system, a multifunctional weather station and so much more. All of the projects described can be built using the components supplied in the Elektor kit.

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 theoretische principes en de basisschakelingen van digitale technieken: signalen, bits en binaire getallen propositielogica en Booleaanse algebra schakelalgebra het vereenvoudigen van schakelingen combinatorische en sequentiële schakelingen parameters halfgeleidertechnologieën signaalwegen geïntegreerde schakelingen impulsen kloksystemen initialisatie combinatorische basisschakelingen latches en flipflops registers adresseerbare geheugens sequentiële basisschakelingen

Grundlagen und Selbstbau Weshalb nicht damit beginnen, Mikrocontroller-Module selbst zu entwickeln, zumindest aber sich in Gedanken mit solchen Aufgaben zu beschäftigen? Wie Mikrocontroller-Module aufgebaut sind und wozu sie verwendet werden, soll in 'Mikrocontroller-Module – Grundlagen und Selbstbau' dargestellt werden. Das vorliegende Buch beleuchtet Mikrocontroller-Module, die vor allem zum Experimentieren, zum Lernen und zum Einarbeiten in die Entwicklung und Programmierung von Embedded Systems gedacht sind. Die Entwurfsgrundsätze, Lösungsvorschläge und Projekte, die in diesem Buch beschrieben werden, sind aus zwei Ideen hervorgegangen: Erstens können neue Entwicklungen zwischen den weit verbreiteten kostengünstigen Mikrocontroller-Modulen und der industriellen Computer- und Steuerungstechnik ihren Platz finden und zweitens ist es eine Herausforderung an sich, solche Module zu entwickeln und einzusetzen. In den ersten sieben Kapiteln dieses Buches werden die technischen Grundlagen diskutiert und anhand eigener Entwicklungen veranschaulicht. Das achte Kapitel gibt einen Überblick über diesen Modulbaukasten. Alle Fotos aus dem Buch können hier vierfarbig heruntergeladen werden.

Developing CoAP applications for Thread networks with Zephyr This book will guide you through the operation of Thread, the setup of a Thread network, and the creation of your own Zephyr-based OpenThread applications to use it. You’ll acquire knowledge on: The capture of network packets on Thread networks using Wireshark and the nRF Sniffer for 802.15.4. Network simulation with the OpenThread Network Simulator. Connecting a Thread network to a non-Thread network using a Thread Border Router. The basics of Thread networking, including device roles and types, as well as the diverse types of unicast and multicast IPv6 addresses used in a Thread network. The mechanisms behind network discovery, DNS queries, NAT64, and multicast addresses. The process of joining a Thread network using network commissioning. CoAP servers and clients and their OpenThread API. Service registration and discovery. Securing CoAP messages with DTLS, using a pre-shared key or X.509 certificates. Investigating and optimizing a Thread device’s power consumption. Once you‘ve set up a Thread network with some devices and tried connecting and disconnecting them, you’ll have gained a good insight into the functionality of a Thread network, including its self-healing capabilities. After you’ve experimented with all code examples in this book, you’ll also have gained useful programming experience using the OpenThread API and CoAP.
