Grove is an open-source, modulated, and ready-to-use toolset and takes a building block approach to assemble electronics. This Kit includes a Base Shield to which the various Grove modules can be connected both individually, or together in various combinations to create fun and exciting projects. All of the modules use a Grove connector, which connects each of the components to a Base Shield in just a few seconds. The Base Shield can then be mounted onto an Arduino UNO board and can be programmed using the Arduino IDE. Instructions for connecting and programming the different modules are also included in this kit. This kit was elaborated in collaboration with Seeed Studio and provides the Arduino community with the opportunity to build projects with minimal effort of both wiring and coding. This kit acts as a bridge to the world of Grove and provides a flexible way for Makers to extend their projects to include other complex Grove modules. The Kit comes includes access to an online platform with all the instructions required to plug, sketch and play with the different Grove Modules. Please note: This kit does not include the Arduino Uno board. Included 1 Base Shield that is designed to fit on top of an Arduino UNO board. It comes equipped with 16 grove connectors, which, when placed on top of the UNO, provides the functionality to various pins. It includes: 7x digital connections 4x analog connections 4x I²C connections 1x UART connection 10 Grove modules included can be connected to the base shield, either through the digital, analog, or I2C connectors on the shield. Let's take a quick look at them: The LED - a simple LED that can be turned ON or OFF, or dimmed. The button - pushbutton can either be in a HIGH or LOW state. The potentiometer - a variable resistor that increases or decreases resistance when turning its knob. The buzzer - a piezo speaker that is used to produce binary sounds. The light sensor - a photoresistor that reads light intensity. The sound sensor - a tiny microphone that measures sound vibrations. The air pressure sensor - reads air pressure, using the I²C protocol. The temperature sensor - reads temperature and humidity at the same time. The accelerometer - a sensor used for orientation, used for detecting movement. The OLED screen - a screen that values or messages can be printed to. 6 Grove cables allow you to easily connect the modules to the Base Shield without any soldering required. The Arduino Sensor Kit Library is a wrapper that contains links to other libraries related to certain modules such as the accelerometer, air pressure sensor, temperature sensor, and OLED display. This library provides easy-to-use APIs that will help you build a clear mental model of the concepts you will be using.
Make your project dreams come true: an odometer for the hamster wheel, a fully automatic control of your ant farm with web interface, or the Sandwich-O-Mat – a machine that toasts and grills sandwiches of your choice.
With the Arduino and the DIY or Maker movement, not only did entry into microcontroller programming become child's play, but a second development also took place: Resourceful developers brought small boards – so-called shields or modules – to the market, which greatly simplified the use of additional hardware. The small modules contain all the important electronic parts to be connected to the microcontroller with a few plug-in cables, eliminating the need for a fiddly and time-consuming assembly on the plug-in board. In addition, it is also possible to handle tiny components that do not have any connecting legs (so-called SMDs).

The Future of Arduino
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
An 8-in-1 test & measurement instrument for the electronics workbench
A well-equipped electronics lab is crammed with power supplies, measuring devices, test equipment and signal generators. Wouldn‘t it be better to have one compact device for almost all tasks? Based on the Arduino, a PC interface is to be developed that’s as versatile as possible for measurement and control. It simply hangs on a USB cable and – depending on the software – forms the measuring head of a digital voltmeter or PC oscilloscope, a signal generator, an adjustable voltage source, a frequency counter, an ohmmeter, a capacitance meter, a characteristic curve recorder, and much more.
The circuits and methods collected here are not only relevant for exactly these tasks in the "MSR" electronics lab, but many details can also be used within completely different contexts.

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 so far, and this workhorse has been with us for many years. Recently, the new Arduino Uno R4 was released, based on a 48-MHz, 32-bit Cortex-M4 processor with a huge amount of SRAM and flash memory. Additionally, a higher-precision ADC and a new DAC are added to the design. The new 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, which are available as a kit from Elektor. 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
4×4 Keypad
Real-time clock (RTC)
Joystick
8×8 LED matrix
Motors
DAC (Digital-to-analog converter)
