RFID technology has conquered many areas in which barcodes, magnetic strips and contact smartcards were used previously. Everyday applications, such as electronic ticketing, access cards, debit cards and electronic identity documents would not be possible without this technology. MIFARE is the most widely used RFID technology, and this book provides a practical and comprehensive introduction to it. Among other things, the initial chapters cover physical fundamentals, relevant standards, RFID antenna design, security considerations and cryptography. The complete design of a reader’s hardware and software is described in detail. The reader’s firmware and the associated PC software support programming using any .NET language. The specially developed PC program, “Smart Card Magic.NET”, is a simple development environment that supports sending commands to a card at the click of a mouse, as well as the ability to create C# scripts. Alternatively, one may follow all of the examples using Visual Studio 2010 Express Edition. Finally, the major smart card reader API standards are introduced. The focus is on programming contactless smartcards using standard PC/SC readers using C/C++, Java and C#.

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.

Analogue Electronics and Microcontrollers Projects Hobbyist electronics can be a fun way to learn new skills that can be helpful to your career. Those who understand the basics of electronics can design their own circuits and projects. However, before you run, you need to learn to walk. It all starts with analogue electronics. You should be familiar with the simple components and circuits and understand their basic behaviors and the issues you may encounter. The best way to do this is through real experiments. Theory alone is not enough. This book offers a large number of practical entry-level circuits, with which everyone can gain the basic experience. Through the widespread introduction of microcontrollers, a new chapter in electronics has begun. Microcontrollers are now performing more and more tasks that were originally solved using discrete components and conventional ICs. Starting out has become easier and easier thanks to platforms including Bascom, Arduino, micro:bit. The book introduces numerous manageable microcontroller applications. It’s now a case of less soldering and more programming.

Learn programming for Alexa devices, extend it to smart home devices and control the Raspberry Pi The book is split into two parts: the first part covers creating Alexa skills and the second part, designing Internet of Things and Smart Home devices using a Raspberry Pi. The first chapters describe the process of Alexa communication, opening an Amazon account and creating a skill for free. The operation of an Alexa skill and terminology such as utterances, intents, slots, and conversations are explained. Debugging your code, saving user data between sessions, S3 data storage and Dynamo DB database are discussed. In-skill purchasing, enabling users to buy items for your skill as well as certification and publication is outlined. Creating skills using AWS Lambda and ASK CLI is covered, along with the Visual Studio code editor and local debugging. Also covered is the process of designing skills for visual displays and interactive touch designs using Alexa Presentation Language. The second half of the book starts by creating a Raspberry Pi IoT 'thing' to control a robot from your Alexa device. This covers security issues and methods of sending and receiving MQTT messages between an Alexa device and the Raspberry Pi. Creating a smart home device is described including forming a security profile, linking with Amazon, and writing a Lambda function that gets triggered by an Alexa skill. Device discovery and on/off control is demonstrated. Next, readers discover how to control a smart home Raspberry Pi display from an Alexa skill using Simple Queue Service (SQS) messaging to switch the display on and off or change the color. A node-RED design is discussed from the basic user interface right up to configuring MQTT nodes. MQTT messages sent from a user are displayed on a Raspberry Pi. A chapter discusses sending a proactive notification such as a weather alert from a Raspberry Pi to an Alexa device. The book concludes by explaining how to create Raspberry Pi as a stand-alone Alexa device.
