After installing Arduino, you might also want to install the drivers (link given below) for your Arduino to communicate with your Computer.

The first step would be to install the Arduino IDE which is available for download for free from the below link. All you need the Arduino IDE, an USB cable and your Nano board itself. It will hardly take 5-10 minutes to upload your first program to Arduino Nano. These special functions and their respective pins are illustrated in the Arduino Nano pinout diagram shown above. Reset Pin: Making this pin LOW, resets the microcontroller.AREF: Used to provide reference voltage for analog inputs with analogReference() function.I2C A4 (SDA) and A5 (SCA): Used for IIC communication using Wire library.When pin 13 is HIGH вЂ“ LED is on and when pin 13 is LOW, it is off. In-built LED Pin 13: This pin is connected with a built-in LED.SPI Pins 10 (SS), 11 (MOSI), 12 (MISO) and 13 (SCK): These pins are used for SPI communication.

PWM Pins 3, 5, 6, 9 and 11: These pins provide an 8-bit PWM output by using analogWrite() function.External Interrupt Pins 2 and 3: These pins can be configured to trigger an interrupt on a low value, a rising or falling edge, or a change in value.

They are connected with the corresponding ATmega328P USB to TTL serial chip.

Serial Pins 0 (Rx) and 1 (Tx): Rx and Tx pins are used to receive and transmit TTL serial data.

These pins apart from serving their purpose, can also be used for special purposes, which are discussed below: The analog pins can measure analog voltage from 0V to 5V using any of the 8 Analog pins using a simple function like analogRead(). The operating voltage is 0V and 5V for digital pins. A simple function like pinMode() and digitalWrite() can be used to control their operation. The digital pins can be used to interface sensors by using them as input pins or drive loads by using them as output pins. There are totalВ 14 digital Pins and 8 Analog pins on your Nano board. +5V Pin: If you have a regulated +5V supply then you can directly provide this o the +5V pin of the Arduino. The on-board voltage regulator regulates it to +5V. Vin Pin: The Vin pin can be supplied with an unregulated 6-12V to power the board. USB Jack: Connect the mini USB jack to a phone charger or computer through a cable and it will draw power required for the board to function

There are totalВ three ways by which you can power your Nano. This board especially is breadboard friendly, and that's why it is very easy to handle the connections. The Arduino board is designed in such a way that it is very easy for beginners to get started with microcontrollers. The technical difference between Nano and Mega is shown below. Arduino Mega is normally used for projects which require a lot of I/O pins and different communication protocols. As you might guess, the size is also bigger than an Arduino UNO. Arduino Mega is more powerful than an Arduino Nano in terms of speed and number of I/O pins. There is a considerable amount of difference between the Arduino Nano and the Arduino mega as the processor used itself is different. The technical difference between Uno and Nano is shown below:Дifference between Arduino Nano and Arduino Mega To program an Uno, you need a Regular USB cable В whereas for Nano, you will need a mini USB cable. Also, Nano is breadboard friendly while Uno is not. UNO is twice as big as Nano and hence occupies more space on your project. One big difference between both is the size.

They use the same Processor (Atmega328p) and hence they both can share the same program. The Arduino Nano is very much similar to the Arduino UNO.
