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.

Einführung in die SPS-Programmierung mit dem Open-Source-Projekt auf dem Raspberry Pi und Modbus-Beispiele mit dem Arduino Uno und ESP8266 Die SPS-Programmierung ist heute in der Industrie und in der Hausautomation sehr weit verbreitet. In diesem Buch beschreibt der Autor, wie der Raspberry Pi 4 als SPS eingesetzt werden kann. Angefangen mit der Softwareinstallation auf dem Raspberry Pi und dem SPS-Editor auf dem PC geht es nach einer Beschreibung der Hardware an das Programmieren. Es folgen interessante Beispiele nach IEC 61131-3 in den verschiedenen Programmiersprachen. Ausführlich wird auch erklärt, wie der SPS-Editor benutzt wird und wie die Programme auf den Raspberry Pi geladen und ausgeführt werden. Angefangen mit der Programmierung mit KOP (Kontaktplan) über ST (Structured Control Language) bis zu AS (Special Function Chart) werden alle IEC-Sprachen mit Beispielen behandelt. Diese können auf der Website des Autors heruntergeladen werden. Auch die Vernetzung kommt nicht zu kurz. Der Arduino Uno und der ESP8266 werden als ModbusRTU- bzw. ModbusTCP-Module programmiert, um Zugriff auf externe Peripherie zu erhalten. Damit ist es möglich, Sensoren einzulesen und Verbraucher zu schalten. Interessant dürften auch E/A-Schaltungen sein, die dem 24V-Industriestandard entsprechen. Befehlsübersichten für ST und KOP runden das Buch ab. Nach dem Durcharbeiten des Buches ist der Leser in der Lage, eigene SPS-Steuerungen mit dem Raspberry Pi zu verwirklichen.

Cool Projects for Test, Measurement, and Control The Raspberry Pi has dominated the maker scene for many years. Freely accessible I/O pins have made it one of the most popular processor boards of all time. However, the classic Raspberry Pi has no analog inputs. Direct measurement of analog values is therefore not possible. Consequently, photodiodes, NTCs, Hall sensors, etc. cannot be read directly. In addition, the pins are connected directly to the exposed contacts, i.e. without a driver or protection circuit. This can quickly destroy the central controller and thus the entire Raspberry Pi. These problems can be elegantly solved with the Pico. As a front-end, it can easily handle a wide range of measurement tasks. In addition, the Pico is much cheaper than a classic Raspberry Pi 4 or 5. If a faulty circuit leads to the destruction of the Pico, this is relatively easy to handle. This makes the combination of a classic Raspberry Pi 4 or 5 and the Pico an ideal pair. The book introduces the broad and highly topical field of modern controller technology using the combined force of a Raspberry Pi 4 or 5 and a Raspberry Pi Pico. In addition to a detailed introduction to the operation and functionality of the controller boards themselves, the book also focuses on data acquisition and processing with digital processors. Especially the combination of both systems offers a wide range of interesting possibilities. Some practical projects from the contents: USB between Raspberry Pi 4 or 5 and Pico I²C Communication and Pico as an I²C device Voltmeter and Computer Thermometer Pico W as a Web Server and WLAN Scanner Frequency Meters and Generators OLED Displays on Raspberry Pi 4 or 5 and Pico Energy Saving Monitor Which Astronauts are in Orbit?

This book describes how the Raspberry Pi 4 can be used as a Programmable Logic Controller. Before taking you into the programming, the author starts with the software installation on the Raspberry Pi and the PLC editor on the PC, followed by a description of the hardware. You'll then find interesting examples in the different programming languages complying with the IEC 61131-3 standard. This manual also explains in detail how to use the PLC editor and how to load and execute the programs on the Raspberry Pi. All IEC languages are explained with examples, starting with LD (Ladder Diagram) over ST (Structured Control Language) to SFC (Special Function Chart). All examples can be downloaded from the author's website. Networking gets thorough attention too. The Arduino Uno and the ESP8266 are programmed as ModbusRTU or ModbusTCP modules to get access to external peripherals, reading sensors and switching electrical loads. I/O circuits complying with the 24 V industry standard may also be of interest for the reader. The book ends with an overview of commands for ST and LD. After reading the book, the reader will be able to create his own controllers with the Raspberry Pi.

Het boek “Sensoren aan de Raspberry Pi” richt zich tot iedereen die zich wil verdiepen in een Raspberry Pi in combinatie met Windows 10 IoT Core. Dit besturingssysteem biedt samen met een RPi weliswaar veel rekenkracht, maar voor de communicatie met de buitenwereld zijn nog externe modules en sensoren nodig. Daartoe wordt in dit boek gebruik gemaakt van een sensor-kit met 35 modules die nog geen 60 euro kost. Auteur Florian Schäffer begint zijn boek met de introductie van de Raspberry Pi en hij beschrijft welke hardware u nodig hebt om met de RPi te kunnen werken. Dan volgt een eerste kennismaking met Windows 10 IoT Core. Daarna wordt dieper ingegaan op het gebruik van Visual Studio 2015 en worden de eerste programmeervoorbeelden beschreven. Ook wordt uitgelegd hoe een MySQL-databank kan worden aangestuurd via een app en hoe de als webserver kan worden ingezet. In het tweede deel worden de sensoren stuk voor stuk beschreven met hun eigenschappen en worden er veel toepassingsvoorbeelden gegeven. De source-codes van de programma’s zijn als download bij het boek beschikbaar. Tot slot wordt nog aandacht besteed aan het gebruik van druktoetsen en schakelaars, en het werken met digitale uitgangen en analoge ingangen.
