ModbusRTU and ModbusTCP examples with the Arduino Uno and ESP8266 Introduction to PLC programming with OpenPLC, the first fully open source Programmable Logic Controller on the Raspberry Pi, and Modbus examples with Arduino Uno and ESP8266 PLC programming is very common in industry and home automation. 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.

A Handbook on DIY Nowadays, security problems are rarely properly solved or correctly addressed. Electronic security is only part of the chain in making a system secure. Electronic security is usually addressed as network or software security, neglecting other aspects, but the chain is only as strong as its weakest link. This book is about electronic hardware security, with an emphasis on problems that you can solve on a shoestring DIY budget. It deals mostly with secure communications, cryptosystems, and espionage. You will quickly appreciate that you can’t simply buy a trustworthy and reliable cryptosystem off the shelf. You will then realise that this applies equally to individuals, corporations, and governments. If you want to increase your electronic security awareness in a world already overcrowded with networks of microphones and cameras, this is a book for you. Furthermore, if you want to do something DIY by designing and expanding upon simple electronic systems, please continue reading. Some of the devices described are already published as projects in the Elektor magazine. Some are still ideas yet to be worked out. Complexity is the main enemy of security, so we'll try to keep to simple systems. Every chapter will analyse real-life espionage events or at least several hypothetical scenarios that will hopefully spark your imagination. The final goal is to build a security-conscious mindset (or “to get into a head of a spy”) which is necessary to recognise possible threats beforehand, to design a truly secure system. Don’t bother reading if: you think you and your secrets are 100% safe and secure you think somebody else can effectively handle your security you think conspiracy theories only exist in theory – Telefunken’s masterpiece the “FS-5000 Harpoon” was built on one!

This board allows the Raspberry Pi Pico (connected via pin header) to drive two motors simultaneously with full forward, reverse & stop control, making it ideal for Pico controlled buggy projects. Alternatively, the board can be used to power a stepper motor. The board features the DRV8833 motor driver IC, which has built-in short circuit, over current and thermal protection. The board has 4 external connections to GPIO pins and a 3 V and GND supply from the Pico. This allows for additional IO options for your buggy builds that can be read or controlled by the Pico. In addition there is an on/off switch and power status LED, allowing you to see at a glance if the board is powered up and save your batteries when your project is not in use. To use the motor driver board, the Pico should have a soldered pin header and be inserted firmly into the connector. The board produces a regulated supply that is fed into the 40-way connector to power the Pico, removing the need to power the Pico directly. The motor driver board is powered via either screw terminals or a servo style connector. Kitronik has developed a micro-python module and sample code to support the use of the Motor Driver board with the Pico. This code is available in the GitHub repo. Features A compact yet feature-packed board designed to sit at the heart of your Raspberry Pi Pico robot buggy projects. The board can drive 2 motors simultaneously with full forward, reverse, and stop control. It features the DRV8833 motor driver IC, which has built-in short circuit, over current and thermal protection. Additionally, the board features an on/off switch and power status LED. Power the board via a terminal block style connector. The 3V and GND pins are also broken out, allowing external devices to be powered. Code it with MicroPython via an editor such as the Thonny editor. Dimensions: 63 mm (L) x 35 mm (W) x 11.6 mm (H) Download Datasheet

Measuring conducted emission is the simplest and most affordable method of getting some indication of whether a design can meet EMI/EMC requirements. A Line Impedance Stabilization Network (LISN) is an indispensable part of an EMC pre-compliance test setup. In cooperation with Würth Elektronik, Elektor has developed a 5 µH, 50 Ω Dual DC LISN that supports voltages up to 60 V and currents up to 10 A. The instrument measures RF interferences on both channels (the power supply) by means of 5-μH blocking inductances. The internal 10-dB attenuation network – one in each channel – contains a 3rd-order high-pass filter with a cutoff frequency of 9 kHz to protect the input of instruments like a spectrum analyzer from potentially harmful DC voltages or low frequencies coming from the EUT (Equipment Under Test).
