Arduino Nano is a small, complete, flexible and breadboard-friendly Microcontroller board, based on ATmega328p, developed by Arduino.cc in Italy in 2008 and contains 30 male I/O headers, configured in a DIP30 style.
Arduino Nano Pinout contains 14 digital pins, 8 analog Pins, 2 Reset Pins & 6 Power Pins.
It is programmed using Arduino IDE, which can be downloaded from Arduino Official site.
Arduino Nano is simply a smaller version of Arduino UNO, thus both have almost the same functionalities.
Arduino Nano’s maximum current rating is 40mA, so the load attached to its pins shouldn’t draw current more than that.
Each of these Digital & Analog Pins is assigned with multiple functions but their main function is to be configured as Input/Output.
Arduino Pins are acted as Input Pins when they are interfaced with sensors, but if you are driving some load then we need to use them as an Output Pin.
Functions like pinMode() and digitalWrite() are used to control the operations of digital pins while analogRead() is used to control analog pins.
The analog pins come with a total resolution of 10-bits which measures the value from 0 to 5V.
Arduino Nano comes with a crystal oscillator of frequency 16 MHz. It is used to produce a clock of precise frequency using constant voltage.
There is one limitation of using Arduino Nano i.e. it doesn’t come with a DC power jack, which means you can not supply an external power source through a battery.
This board doesn’t use standard USB for connection with a computer, instead, it comes with Type-B Micro USB.
The tiny size and breadboard-friendly nature make this device an ideal choice for most applications where the size of the electronic components is of great concern.
Flash memory is 16KB or 32KB that all depends on the Atmega board i.e Atmega168 comes with 16KB of flash memory while Atmega328 comes with a flash memory of 32KB. Flash memory is used for storing code. The 2KB of memory out of total flash memory is used for a bootloader.
The SRAM memory of 2KB is present in Arduino Nano.
Arduino Nano has an EEPROM memory of 1KB.
Arduino Nano is a very useful device that comes with a wide range of applications and covers less space as compared to other Arduino boards. Breadboard-friendly nature makes it stand out from other boards. Following are the main applications of Arduino Nano:
