Dieses Buch ist eine Einführung in das hochaktuelle Gebiet der Robotik. Dabei stehen praktische Anwendungsbeispiele im Vordergrund. Neben den technischen und mechanischen Grundlagen werden die elektronischen Komponenten und Module erläutert. Eine zentrale Rolle spielt dabei der Mikrocontroller. Für Robotik-Anwendungen haben sich zwei Controller-Boards etabliert: der Arduino und der Raspberry Pi. Dem trägt dieses Buch Rechnung und beschreibt praktische Nachbauprojekte mit diesen beiden populären Boards. Getreu der Philosophie des „Learning by Doing“ können sich auch ambitionierte, nichtprofessionelle Anwender mit dem Lernmaterial des Buches einen Überblick über den neuesten Stand der Robotertechnik und KI verschaffen. Für praktische Anwendungen können sowohl komplette Bausätze als auch einzelne Komponenten verwendet werden. Dabei wurde stets darauf geachtet, dass die Hardware möglichst universell einsetzbar ist.

With Examples for Arduino UNO, Raspberry Pi Pico and ESP32 Programming small electronic systems has never been more accessible. Tasks that once demanded expensive tools, specialized hardware, and deep electrical engineering expertise can now be tackled with low-cost development boards and approachable software. At the centre of this shift is the Arduino environment, which provides a unified and familiar way to program a wide range of microcontroller platforms—from classic AVR boards like the Arduino UNO to modern ARM-based boards such as the Raspberry Pi Pico, and powerful Wi-Fi-enabled devices like the ESP32. This book introduces embedded programming through the core idea that defines all microcontrollers: reading inputs, processing information, and controlling outputs in a predictable loop. The Arduino environment abstracts much of the hardware complexity, allowing you to focus on behaviour rather than implementation details. With just a few lines of code, you can blink LEDs, read sensors, control motors, and communicate with other devices. While the Arduino UNO, Raspberry Pi Pico, and ESP32 boards differ greatly in performance and features, they share the same fundamental building blocks: digital and analog I/O, timers, serial communication, PWM, interrupts, and power management. Learning these concepts within the Arduino framework builds skills that transfer easily across platforms and scale toward more advanced applications. By exploring multiple boards while maintaining a consistent programming approach, this book helps you progress from simple experiments to confidently produce well-structured designs—showing that embedded development can be both practical and enjoyable.

Affordable solutions with the ESP8266 and 3D printing If you are looking for a small yet powerful IoT device, you are likely to come across the ESP8266 and compatible products on the market today. One of these, the Wemos/Lolin D1 Mini Pro board strikes a remarkable balance between cost and performance. A small and very affordable prototype board, the D1 Mini Pro stands out with its WiFi functionality and a 16-Mbytes flash memory for easy creation of a flash file system. In addition, there are sufficient input and output pins (only one analog input though) to support PWM, I²C, and One-Wire systems to mention but a few. The book describes the operation, modding, construction, and programming of home appliances including a colorful smart home accessory, a refrigerator/greenhouse controller, an AC powerline monitor, a door lock monitor, and an IKEA Trådfri controller. As a benefit, all firmware developed for these DIY, "IoT-ized" devices can be updated over-the-air (OTA). For most of the designs in the book, a small printed circuit board (PCB) and an enclosure are presented so readers can have a finished and attractive-looking product. Readers having – or with access to! – a 3D printer can "print" the suggested enclosures at home or in a shop. Some of the constructions benefit from a Raspberry Pi configured as a gateway or cms server. This is also described in detail with all the necessary configuring. You don’t need to be an expert but the prerequisites to successful replication of the projects include basic skills with PC software including the ability to surf the Internet. In terms of hardware, you should be comfortable with soldering and generally assembling the PCBs presented in the book. All custom software written for the IoT devices, the PCB layouts, and 3D print files described in the book are available for free downloading.

The Elektor Super Servo Tester can control servos and measure servo signals. It can test up to four servo channels at the same time. The Super Servo Tester comes as a kit. All the parts required to assemble the Super Servo Tester are included in the kit. Assembling the kit requires basic soldering skills. The microcontroller is already programmed. The Super Servo Tester features two operating modes: Control/Manual and Measure/Inputs. In Control/Manual mode the Super Servo Tester generates control signals on its outputs for up to four servos or for the flight controller or ESC. The signals are controlled by the four potentiometers. In Measure/Inputs the Super Servo Tester measures the servo signals connected to its inputs. These signals may come from for instance an ESC, a flight controller, or the receiver or another device. The signals are also routed to the outputs to control the servos or the flight controller or ESC. The results are shown on the display.
