Two reasons can be identified for the immense success of the Arduino platform. First, the cheap, ready to go processor board greatly simplifies the introduction to hardware. The second success factor is the free and open-source programming suite that does not require an installation procedure. Simple entry-level examples ensure rapid successes. Complex selection procedures for parameters like the microprocessor version or interface settings are not required. The first sample programs can be uploaded to the Arduino board, and tested, in a matter of minutes. The Arduino user is supported by an array of software libraries. However, the daily increasing volume of libraries poses initial problems to the newcomer, and the way ahead may be uncertain after a few entry-level examples. In many cases, detailed descriptions are missing, and poorly described projects tend to confuse rather than elucidate. Clear guidance and a single motto are missing, usually owing to the projects having been created by several different persons—all with different aims in mind. This book represents a different approach. All projects are presented in a systematical manner, guiding into various theme areas. In the coverage of must-know theory great attention is given to practical directions users can absorb, including essential programming techniques like A/D conversion, timers and interrupts—all contained in the hands-on projects. In this way readers of the book create running lights, a wakeup light, fully functional voltmeters, precision digital thermometers, clocks of many varieties, reaction speed meters, or mouse controlled robotic arms. While actively working on these projects the reader gets to truly comprehend and master the basics of the underlying controller technology.

Third, extended and revised edition with AVR Playground and Elektor Uno R4 Arduino boards have become hugely successful. They are simple to use and inexpensive. This book will not only familiarize you with the world of Arduino but it will also teach you how to program microcontrollers in general. In this book theory is put into practice on an Arduino board using the Arduino programming environment. Some hardware is developed too: a multi-purpose shield to build some of the experiments from the first 10 chapters on; the AVR Playground, a real Arduino-based microcontroller development board for comfortable application development, and the Elektor Uno R4, an Arduino Uno R3 on steroids. The author, an Elektor Expert, provides the reader with the basic theoretical knowledge necessary to program any microcontroller: inputs and outputs (analog and digital), interrupts, communication busses (RS-232, SPI, I²C, 1-wire, SMBus, etc.), timers, and much more. The programs and sketches presented in the book show how to use various common electronic components: matrix keyboards, displays (LED, alphanumeric and graphic color LCD), motors, sensors (temperature, pressure, humidity, sound, light, and infrared), rotary encoders, piezo buzzers, pushbuttons, relays, etc. This book will be your first book about microcontrollers with a happy ending! This book is for you if you are a beginner in microcontrollers, an Arduino user (hobbyist, tinkerer, artist, etc.) wishing to deepen your knowledge,an Electronics Graduate under Undergraduate student or a teacher looking for ideas. Thanks to Arduino the implementation of the presented concepts is simple and fun. Some of the proposed projects are very original: Money Game Misophone (a musical fork) Car GPS Scrambler Weather Station DCF77 Decoder Illegal Time Transmitter Infrared Remote Manipulator Annoying Sound Generator Italian Horn Alarm Overheating Detector PID Controller Data Logger SVG File Oscilloscope 6-Channel Voltmeter All projects and code examples in this book have been tried and tested on an Arduino Uno board. They should also work with the Arduino Mega and every other compatible board that exposes the Arduino shield extension connectors. Please note For this book, the author has designed a versatile printed circuit board that can be stacked on an Arduino board. The assembly can be used not only to try out many of the projects presented in this book but also allows for new exercises that in turn provide the opportunity to discover new techniques.

An 8-in-1 test & measurement instrument for the electronics workbench A well-equipped electronics lab is crammed with power supplies, measuring devices, test equipment and signal generators. Wouldn‘t it be better to have one compact device for almost all tasks? Based on the Arduino, a PC interface is to be developed that’s as versatile as possible for measurement and control. It simply hangs on a USB cable and – depending on the software – forms the measuring head of a digital voltmeter or PC oscilloscope, a signal generator, an adjustable voltage source, a frequency counter, an ohmmeter, a capacitance meter, a characteristic curve recorder, and much more. The circuits and methods collected here are not only relevant for exactly these tasks in the "MSR" electronics lab, but many details can also be used within completely different contexts.

Programming and Projects for the Minima and WiFi 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.

Concrétisez vos rêves, réalisez les projets les plus fous : un odomètre pour la roue de votre hamster, la surveillance complètement automatisée de votre fourmilière avec interface web, ou le Sandwich-O-Mat ? une machine qui grille les sandwichs de votre choix. Avec les cartes Arduino et le mouvement DIY (« fais-le toi-même ») ou maker, se mettre à programmer des microcontrôleurs est devenu un jeu d?enfant. Une deuxième révolution a eu lieu : des développeurs ingénieux ont mis sur le marché de petites cartes ? appelées « shields » ou modules ? qui simplifient considérablement l?utilisation d?autres dispositifs. Ces petits modules contiennent tous les composants électroniques nécessaires pour la connexion au microcontrôleur ; quelques fils avec des fiches suffisent pour le raccordement, ce qui évite d?avoir à câbler et fait gagner du temps. En outre, il est également possible de manipuler de minuscules composants dépourvus de pattes de connexion (ceux de type CMS).
