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. Arduino Uno R4 WiFi The Arduino Uno R4 is powered by the Renesas RA4M1 32-bit ARM Cortex-M4 processor, providing a significant boost in processing power, memory, and functionality. The WiFi version comes with an ESP32-S3 WiFi module in addition to the RA4M1, expanding creative opportunities for makers and engineers. The Arduino Uno R4 runs at 48 MHz, which provides a 3x increase over the popular Uno R3. Additionally, SRAM has been upgraded from 2 kB to 32 kB, and flash memory from 32 kB to 256 kB to support more complex projects. Responding to community feedback, the USB port is now USB-C, and the maximum power supply voltage has been raised to 24 V with an enhanced thermal design. The board includes a CAN bus and an SPI port, enabling users to reduce wiring and perform parallel tasks by connecting multiple shields. A 12-bit analog DAC is also provided on the board.

Realize your own projects with the Elektor Arduino Nano MCCAB Training Board The microcontroller is probably the most fascinating subfield of electronics. Due to the multitude of functions, it combines on its chip, it is a universal multi-tool for developers to realize their projects. Practically every device of daily use today is controlled by a microcontroller. However, for an electronic layman, realizing his own ideas with a microcontroller has so far remained a pipe dream due to its complexity. The Arduino concept has largely simplified the use of microcontrollers, so that now even laymen can realize their own electronics ideas with a microcontroller. Book & Hardware in the Bundle: 'Learning by Doing' This book, which is included in the bundle, shows how you can realize your own projects with a microcontroller even without much experience in electronics and programming languages. It is a microcontrollers hands-on course for starters, because after an overview of the internals of the microcontroller and an introduction to the programming language C, the focus of the course is on the practical exercises. The reader acquires the necessary knowledge by 'learning by doing': in the extensive practical section with 12 projects and 46 exercises, what is learned in the front part of the book is underpinned with many examples. The exercises are structured in such a way that the user is given a task to solve using the knowledge built up in the theoretical part of the book. Each exercise is followed by a sample solution that is explained and commented on in detail, which helps the user to solve problems and compare it with his own solution. Arduino IDE The Arduino IDE is a software development environment that can be downloaded for free to your own PC and that contains the entire software package needed for your own microcontroller projects. You write your programs ('apps') with the IDE’s editor in the C programming language. You translate them into the bits and bytes that the microcontroller understands using the Arduino IDE's built-in compiler, and then load them into the microcontroller's memory on the Elektor Arduino MCCAB Nano Training Board via a USB cable. Query or control external sensors, motors or assemblies In addition to an Arduino Nano microcontroller module, the Elektor Arduino Nano MCCAB Training Board contains all the components required for the exercises, such as light-emitting diodes, switches, pushbuttons, acoustic signal transmitters, etc. External sensors, motors or assemblies can also be queried or controlled with this microcontroller training system.
