Mastering the Arduino Uno R4: Programming and Projects for the Minima and WiFi

Description

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 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. The Arduino Uno R3 board probably ranks as the most popular Arduino family member to date and has been with us for many years. Based on the low-cost 8-bit ATmega328P processor, the Uno R3 has been used by students and hobbyists in many beginning and intermediate-level, low-speed projects requiring small to medium amounts of memory. Perhaps one of the attractive points of the Uno R3 was its powerful IDE and the simplicity of using it to develop projects in relatively short times. Recently, the new Arduino Uno R4 was announced. This new board is compatible with the earlier Uno R3 but offers highly improved specifications compared to Uno R3. The new Arduino Uno R4 is based on a 48 MHz 32-bit Cortex-M4 processor with a large amount of SRAM and flash memory. Additionally, a higher-precision ADC and a new DAC are added to the design. The contemporary design also supports the CAN bus 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. The projects given in the book have been fully tested with just a handful of parts and external modules, which are available as a kit from Elektor. The block diagrams, circuit diagrams, full program listings, and complete program descriptions are given for all the projects in the book. You should find it easy to build the project hardware and then follow the software descriptions given for the projects. It should also be relatively easy to modify the hardware and software for your own project applications. 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.
