Datasheet
Manual
The Arduino Nano is a small, complete, and breadboard-friendly board based on the ATmega328 (Arduino Nano 3.x). It has more or less the same functionality of the Arduino Duemilanove but in a different package. It lacks only a DC power jack and works with a Mini-B USB cable instead of a standard one.

Dimensions

Power
The Arduino Nano can be powered via the Mini-B USB connection, 6-20 V unregulated external power supply (pin 30), or 5 V regulated external power supply (pin 27). The power source is automatically selected to the highest voltage source.
Memory
The ATmega168 has 16 KB of flash memory for storing code (of which 2 KB is used for the bootloader), 1 KB of SRAM and 512 bytes of EEPROM
The ATmega328 has 32 KB of flash memory for storing code, (also with 2 KB used for the bootloader), 2 KB of SRAM and 1 KB of EEPROM.
Input and Output
Each of the 14 digital pins on the Nano can be used as an input or output, using pinMode(), digitalWrite(), and digitalRead() functions. They operate at 5 V.
Each pin can provide or receive a maximum of 40 mA and has an internal pull-up resistor (disconnected by default) of 20-50 kOhms.
Communication
The Arduino Nano has a number of facilities for communicating with a computer, another Arduino, or other microcontrollers.
The ATmega168 and ATmega328 provide UART TTL (5V) serial communication, which is available on digital pins 0 (RX) and 1 (TX). An FTDI FT232RL on the board channels this serial communication over USB and the FTDI drivers (included with the Arduino software) provide a virtual com port to software on the computer.
The Arduino software includes a serial monitor which allows simple textual data to be sent to and from the Arduino board. The RX and TX LEDs on the board will flash when data is being transmitted via the FTDI chip and USB connection to the computer (but not for serial communication on pins 0 and 1).
A SoftwareSerial library allows for serial communication on any of the Nano's digital pins.
Programming
The Arduino Nano can be programmed with the Arduino software (download).
The ATmega168 or ATmega328 on the Arduino Nano comes with a bootloader that allows you to upload new code to it without the use of an external hardware programmer. It communicates using the original STK500 protocol (reference, C header files).
You can also bypass the bootloader and program the microcontroller through the ICSP (In-Circuit Serial Programming) header using Arduino ISP or similar; see these instructions for details.
Automatic (Software) Reset
Rather than requiring a physical press of the reset button before an upload, the Arduino Nano is designed in a way that allows it to be reset by software running on a connected computer.
One of the hardware flow control lines (DTR) of theFT232RL is connected to the reset line of the ATmega168 or ATmega328 via a 100 nF capacitor. When this line is asserted (taken low), the reset line drops long enough to reset the chip.
The Arduino software uses this capability to allow you to upload code by simply pressing the upload button in the Arduino environment. This means that the bootloader can have a shorter timeout, as the lowering of DTR can be well-coordinated with the start of the upload.

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.

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.

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
