in 10 captivating lessons Using the lessons in this book you learn how to program a microcontroller. You’ll be using JAL, a free but extremely powerful programming language for PIC microcontrollers, which enjoys great popularity in the hobby world. Starting out from scratch virtually, you slowly build up the knowledge. No previous knowledge is needed: anyone can get started with this book. Assuming you have absorbed all lessons – meaning you have actually completed all the exercises – you should be confident to write PIC microcontroller programs, as well as read and understand programs written by other people. JAL commands You learn the function of JAL commands such as include, pin, delay, forever loop, while loop, case, exit loop, repeat until, if then, as well as the use of functions, procedures and timer- and port interrupts. JAL programs You make an LED blink, build a time switch, measure a potentiometer’s wiper position, produce sounds, suppress contact bounce, and control the brightness of an LED. And of course you learn to debug, meaning: how to spot and fix errors in your programs. Hardware You learn to recognize various components including the PIC microcontroller, potentiometer and quartz crystal, and how to wire up a PIC microcontroller and effectively link it to your PC. A breadboard is used for the purpose, allowing you to easily modify the component arrangement for further experimenting. The companion software with this book can be downloaded free of charge, including the JAL programming language. In addition, you may order a kit of parts so you don’t have to go shopping for the required components. Especially for a beginner, this is the easiest way to start with this unique pastime. Having finished this book does not mean you are through with your pastime. You can get your hands dirty again, and if desired use other books packed with fun projects using the JAL programming language. More information may be found at the end of the lessons in the chapter "Done! What’s next?""

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!

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#.
