Practical Multitasking Fundamentals Programming embedded systems is difficult because of resource constraints and limited debugging facilities. Why develop your own Real-Time Operating System (RTOS) as well as your application when the proven FreeRTOS software is freely available? Why not start with a validated foundation? Every software developer knows that you must divide a difficult problem into smaller ones to conquer it. Using separate preemptive tasks and FreeRTOS communication mechanisms, a clean separation of functions is achieved within the entire application. This results in safe and maintainable designs. Practicing engineers and students alike can use this book and the ESP32 Arduino environment to wade into FreeRTOS concepts at a comfortable pace. The well-organized text enables you to master each concept before starting the next chapter. Practical breadboard experiments and schematics are included to bring the lessons home. Experience is the best teacher. Each chapter includes exercises to test your knowledge. The coverage of the FreeRTOS Application Programming Interface (API) is complete for the ESP32 Arduino environment. You can apply what you learn to other FreeRTOS environments, including Espressif’s ESP-IDF. The source code is available from GitHub. All of these resources put you in the driver’s seat when it is time to develop your next uber-cool ESP32 project. What you will learn: How preemptive scheduling works within FreeRTOS The Arduino startup “loopTask” Message queues FreeRTOS timers and the IDLE task The semaphore, mutex, and their differences The mailbox and its application Real-time task priorities and its effect Interrupt interaction and use with FreeRTOS Queue sets Notifying tasks with events Event groups Critical sections Task local storage The gatekeeper task

Clever Tricks with ATmega328 Pro Mini Boards With a simple Pro Mini board and a few other components, projects that 20 or 30 years ago were unthinkable (or would have cost a small fortune) are realized easily and affordably in this book: From simple LED effects to a full battery charging and testing station that will put a rechargeable through its paces, there’s something for everyone. All the projects are based on the ATmega328 microcontroller, which offers endless measuring, switching, and control options with its 20 input and output lines. For example, with a 7-segment display and a few resistors, you can build a voltmeter or an NTC-based thermometer. The Arduino platform offers the perfect development environment for programming this range of boards. Besides these very practical projects, the book also provides the necessary knowledge for you to create projects based on your own ideas. How to measure, and what? Which transistor is suitable for switching a certain load? When is it better to use an IC? How do you switch mains voltage? Even LilyPad-based battery-operated projects are discussed in detail, as well as many different motors, from simple DC motors to stepper motors. Sensors are another exciting topic: For example, a simple infrared receiver that can give disused remote controls a new lease on life controlling your home, and a tiny component that can actually measure the difference in air pressure between floor and table height!

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, 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.

De Elektor Laserkop transformeert de Elektor Sand Clock in een klok die de tijd op glow-in-the-dark-film schrijft in plaats van op zand. Naast het weergeven van de tijd kan het ook worden gebruikt om kortstondige tekeningen te maken. De 5 mW laserpointer, met een golflengte van 405 nm, produceert heldergroene tekeningen op de glow-in-the-dark-film. Voor het beste resultaat gebruikt u de kit in een slecht verlichte kamer. Waarschuwing: Kijk nooit rechtstreeks in de laserstraal! De kit bevat alle benodigde componenten, maar het solderen van drie draden is vereist. Opmerking: Deze kit is ook compatibel met de originele Arduino-gebaseerde Zandklok uit 2017. Voor meer details, zie Elektor 1-2/2017 en Elektor 1-2/2018.

The SQ series of handsfree PCBite probes from Sensepeek are insulated, come with included color-coded cable holders and have a lower point of gravity making them even more stable compared with the original SP series of probes. All the loved features of handsfree measurement, exchangeable fine pitch spring tipped test needle and the minimalistic design is maintained to make traditional sized and handheld probes obsolete. Features All handsfree probes from Sensepeek makes instant measurements or long triggering sessions a breeze. No more soldering wires to connect your probe or complicated tools to setup, just positioning the probe needle on any test point or component in the signal path and release. Saves time and frustration during development, verification and repairs. The minimalist design and the spring-loaded test needle makes it possible to simultaneously measure on fine pitch components and nearby signals. Both length and weight of the SQ probes are perfectly balanced to be used with the included PCB holders and base plate which is a must for handsfree function. The probe holder comes with a powerful magnet in the base, as for all PCBite probes and holders which makes the probe easy to place and reposition. The SQ series of probes can be used handheld without the probe holder as they have an insulated grip but their full potential is used when measuring handsfree. One side of the included baseplate is matte and the other is mirror polished. The mirror polished surface makes it easy to see components on the circuit board underside. For added protection during measurement the included insulation cover can be mounted on one of the surfaces. Included 4x PCBite PCB holders 1x Set of yellow insulation washers for the PCB holders 1x Large Base plate (A4) 1x Insulation cover for the base plate (A4) 1x Micro fiber cloth 4x SQ10 probes and pin tipped test needles (black) 2x Banana to dupont test wires (red/black) 5x Dupont to dupont test wires 1x Set of cable holders (4 colors) 4x Extra test needles Downloads User guide (PCBite kit) User guide (SQ10 probes)
