Practical Applications and Project with Arduino, ESP32, and RP2040
Immerse yourself in the fascinating world of control engineering with Arduino and ESP32! This book offers you a practical introduction to classic and modern control methods, including PID controllers, fuzzy logic, and sliding-mode controllers.
In the first part, you will learn the basics of the popular Arduino controllers, such as the Arduino Uno and the ESP32, as well as the integration of sensors for temperature and pH measurement (NTC, PT100, PT1000, and pH sensor).
You will learn how to use these sensors in various projects and how to visualize data on a Nextion TFT display. The course continues with an introduction to actuators such as MOSFET switches, H-bridges, and solid-state relays, which are used to control motors and actuators. You will learn to analyze and model controlled systems, including PT1 and PT2 control.
The book focuses on the implementation of fuzzy and PID controllers for controlling temperature and DC motors. Both the Arduino Uno and the ESP32 are used. The sliding-mode controller is also introduced.
In the second-to-last chapter, you will explore the basics of neural networks and learn how machine learning can be used on an Arduino. In the last chapter, there is a practical example of a fuzzy controller for feeding electricity into the household grid.
This book is the perfect choice for engineers, students, and electronics engineers who want to expand their projects with innovative control techniques.
This bundle is all about designing projects based on the 555 timer IC. The book features over 45 fully tested and documented projects. Together with the kit, which contains more than 130 through-hole components, you can build all the projects described on a breadboard. The setup also makes it easy to modify and experiment with the projects.

Firmware V1.0.3
The Elektor Laser Head transforms the Elektor Sand Clock into a clock that writes the time on glow-in-the-dark film instead of sand. In addition to displaying the time, it can also be used to create ephemeral drawings. The 5 mW laser pointer, with a wavelength of 405 nm, produces bright green drawings on the glow-in-the-dark film. For best results, use the kit in a dimly lit room. Warning: Never look directly into the laser beam!
The kit includes all the necessary components, but soldering three wires is required.
Note: This kit is also compatible with the original Arduino-based Sand Clock from 2017. For more details, see Elektor Magazine 1-2/2017 and Elektor Magazine 1-2/2018.

A Combat Guide against E-waste and Throwawayism
This book is for anyone who enjoys tinkering with analog and digital hardware electronics. Regardless of the sophistication of your workspace, only basic tools are required to achieve truly satisfying results. It is intended as a reference guide among other hardware repair publications you may have in your library. However, the book goes a step further than most other repair guides in addressing issues in the modern era of discarded electronics called e-waste.
E-waste should be put to good use. Producing anything new requires not just precious resources and labor, but also energy to make and deliver it to global retail shelves. Your talents and love of electronics can be put to good use by rescuing and resurrecting at least selected units from this endless stream of e-waste. Examples include either restoring through repair, or salvaging reusable electronic and mechanical components for your next project.
Smart tips are provided throughout the book, and much information is tabulated for easy reference. The book expands age-old repair and hacking techniques applied for repair on the workbench into clever methods and applications to achieve effective results with discarded or “non-servicable” electronic consumer products. The final chapter provides real-life examples using all of the previously discussed content in a summarized form for each example repair type.
