Offre groupée : Mastering the Arduino Uno R4

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 so far, and this workhorse has been with us for many years. Recently, the new Arduino Uno R4 was released, based on a 48-MHz, 32-bit Cortex-M4 processor with a huge amount of SRAM and flash memory. Additionally, a higher-precision ADC and a new DAC are added to the design. The new 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, which are available as a kit from Elektor. 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
  • 4×4 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 Minima

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 Uno R4 Minima is an affordable option for those who don't need the additional features.

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.
