Pfiffige Lösungen mit Arduino Pro Mini und ATmega328-Boards Mit einem einfachen Arduino Pro Mini Board und ein paar weiteren Bauteilen lassen sich heute für wenig Geld Projekte realisieren, die vor 20 oder 30 Jahren noch undenkbar waren oder ein kleines Vermögen gekostet hätten. Von einfachen LED-Effekten bis zur Ladestation – die den Akku auf Herz und Nieren prüft – ist in diesem Buch vieles dabei. Als Mikrocontroller dient bei allen beschriebenen Projekten der ATmega328, der mit seinen 20 Ein- und Ausgangsleitungen unzählige Möglichkeiten zum Messen, Schalten und Steuern bietet. Mit einem 7-Segment-Display und ein paar Widerständen lässt sich daraus z. B. ein Voltmeter bauen oder mittels NTC ein Thermometer. Die Arduino-Plattform bietet dabei die perfekte Entwicklungsumgebung zum Programmieren der Boards. Neben den ganz konkreten Projekten soll das Buch aber auch das nötige Wissen vermitteln, um eigene Ideen zu realisieren. Wie misst man was? Welches ist der geeignete Transistor, um verschiedene Verbraucher zu schalten? Wann ist man mit einem IC besser bedient, oder wie schaltet man Netzspannung? Auch batteriebetriebene Projekte mit LilyPad sind ausführlich thematisiert. Ebenso vielerlei Motoren, vom einfachen Gleichstrommotor bis zum Schrittmotor. Sensoren sind ein weiteres spannendes Thema. Nur zwei Beispiele: Mit einem winzigen Bauteil lässt sich tatsächlich messen, dass der Luftdruck am Fußboden höher ist als auf Tischhöhe. Mit einem simplen Infrarot-Empfänger kann man ausgedienten Fernbedienungen ein zweites Leben schenken und die Wohnung damit steuern.

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!

Book: Mastering the Arduino Uno R4 Based on the low-cost 8-bit ATmega328P processor, the Arduino Uno R3 board is likely to score as the most popular Arduino family member, and this workhorse has been with us for many years. Eleven years later, the long-overdue successor, the Arduino Uno R4, was released. It is built around a 48 MHz, 32-bit Arm Cortex-M4 microcontroller and provides significantly expanded SRAM and Flash memory. Additionally, a higher-precision ADC and a new DAC are added to the design. The Uno R4 board also supports the CAN Bus with an interface. Two versions of the board are available: Uno R4 Minima, and Uno R4 WiFi. This book is about using these new boards to develop many different and interesting projects with just a handful of parts and external modules. All projects described in the book have been fully tested on the Uno R4 Minima or the Uno R4 WiFi board, as appropriate. The project topics include the reading, control, and driving of many components and modules in the kit as well as on the relevant Uno R4 board, including LEDs 7-segment displays (using timer interrupts) LCDs Sensors RFID Reader 4x4 Keypad Real-time clock (RTC) Joystick 8×8 LED matrix Motors DAC (Digital-to-analog converter) LED matrix WiFi connectivity Serial UART CAN bus Infrared controller and receiver Simulators … all in creative and educational ways with the project operation and associated software explained in great detail.
