Elektor Publishing Arduino & Co – Measure, Control, and Hack
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!

Elektor Publishing Mastering the Arduino Uno R4
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.

Elektor Digital Embedded in Embedded (E-book)
ARM Cortex-M Embedded Design from 0 to 1 Hobbyists can mash together amazing functional systems using platforms like Arduino or Raspberry Pi, but it is imperative that engineers and product designers understand the foundational knowledge of embedded design. There are very few resources available that describe the thinking, strategies, and processes to take an idea through hardware design and low-level driver development, and successfully build a complete embedded system. Many engineers end up learning the hard way, or never really learn at all. ARM processors are essentially ubiquitous in embedded systems. Design engineers building novel devices must understand the fundamentals of these systems and be able to break down large, complicated ideas into manageable pieces. Successful product development means traversing a huge amount of documentation to understand how to accomplish what you need, then put everything together to create a robust system that will reliably operate and be maintainable for years to come. This book is a case study in embedded design including discussion of the hardware, processor initialization, low‑level driver development, and application interface design for a product. Though we describe this through a specific application of a Cortex-M3 development board, our mission is to help the reader build foundational skills critical to being an excellent product developer. The completed development board is available to maximize the impact of this book, and the working platform that you create can then be used as a base for further development and learning. The Embedded in Embedded program is about teaching fundamental skill sets to help engineers build a solid foundation of knowledge that can be applied in any design environment. With nearly 20 years of experience in the industry, the author communicates the critical skill development that is demanded by companies and essential to successful design. This book is as much about building a great design process, critical thinking, and even social considerations important to developers as it is about technical hardware and firmware design.
