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!

Make your project dreams come true: an odometer for the hamster wheel, a fully automatic control of your ant farm with web interface, or the Sandwich-O-Mat – a machine that toasts and grills sandwiches of your choice. With the Arduino and the DIY or Maker movement, not only did entry into microcontroller programming become child's play, but a second development also took place: Resourceful developers brought small boards – so-called shields or modules – to the market, which greatly simplified the use of additional hardware. The small modules contain all the important electronic parts to be connected to the microcontroller with a few plug-in cables, eliminating the need for a fiddly and time-consuming assembly on the plug-in board. In addition, it is also possible to handle tiny components that do not have any connecting legs (so-called SMDs).

Microcontrollers have become an indispensable part of modern electronics. They make things possible that vastly exceed what could be done previously. Innumerable applications show that almost nothing is impossible. There’s thus every reason to learn more about them, but that raises the question of where to find a good introduction to this fascinating technology. The answer is easy: this Microcontroller Basics book, combined with the 89S8252 Flash Board project published by Elektor Electronics. However, this book offers more than just a basic introduction. It clearly explains the technology using various microcontroller circuits and programs written in several different programming languages. Three microcontrollers from the 8051 family are used in the sample applications, ranging from the simple 89C2051 to the AN2131, which is designed to support USB applications. The programming tools include assemblers, Basic-52 and BASCOM-51, and several C compilers. Every reader can thus find the programming environment most suitable to his or her needs. In the course of the book, the reader gradually develops increased competence in converting his or her ideas into microcontroller circuitry. All of the sample programs can be downloaded from the Elektor Electronics website or the author’s website. That has the added advantage that the latest versions are always available.

Der Autor zeigt in diesem Buch alle wichtigen Aspekte der Mikrocontroller-Programmierung, ohne den Leser mit unnötigen oder nebensächlichen Informationen zu überladen. Am Ende der Lektüre ist der Leser in der Lage, 8-Bit-Mikrocontroller zu verstehen und zu programmieren. Die Einführung in die Mikrocontroller-Programmierung dekliniert der Autor an Mikrocontrollern aus der PIC-Familie durch. Der PIC mit seinem 8-Bit-Design ist nicht auf dem modernsten technischen Stand, aber dafür einfach zu verstehen. Er wird in einem DIP-Gehäuse angeboten, ist überall erhältlich und nicht besonders komplex. Das gesamte Datenblatt des PICs ist um Dekaden kürzer als die Architekturbeschreibung, die den Prozessor eines fortgeschrittenen Mikrocontrollers beschreibt. Die Einfachheit hat ihre Vorteile. Wer versteht, wie ein Mikrocontroller grundlegend funktioniert, kann sich später in fortgeschrittene Softcores einarbeiten. Steht im ersten Teil des Buches Assembler als ausführende Programmiersprache im Vordergrund, so geht der Autor im zweiten Teil seines Buches vertiefend auf C ein. Quasi nebenbei entführt das Buch den Leser in die Tiefen der praktischen Arbeit mit Mikrocontrollern, erklärt interessante Messtechnik und zeigt Möglichkeiten zur Arbeitserleichterung und Fehlersuche.
