Power Pin (Vin, 3.3V, 5V, GND): These pins are power pins

Vin is the input voltage of the board, and it is used when an external power source is used from 7V to 12V.

5V is the regulated power supply voltage of the nano board and it is used to give the supply to the board as well as components.

3.3V is the minimum voltage which is generated from the voltage regulator on the board.

RST Pin( Reset): This pin is used to reset the microcontrollerĮxternal Interrupts (2, 3): These pins are used to activate an interrupt. PWM (3, 5, 6, 9, 11): These pins are used to provide 8-bit of PWM output. SPI (10, 11, 12, & 13): These pins are used for supporting SPI communication. IIC (A4, A5): These pins are used for supporting TWI communication.ĪREF: This pin is used to give reference voltage to the input voltage Difference between Arduino UNO and Arduino Nano Inbuilt LED (13): This pin is used to activate the LED.

The Arduino Nano board is similar to an Arduino UNO board including similar microcontroller like Atmega328p. The main difference between these two is the size. Because Arduino Uno size is double to nano board. So Uno boards use more space on the system. The programming of UNO can be done with a USB cable whereas Nano uses the mini USB cable. difference-between-Arduino-UNO-and-Arduino-nano Arduino Nano Communication The main differences between these two are listed in the following table. The communication of an Arduino Nano board can be done using different sources like using an additional Arduino board, a computer, otherwise using microcontrollers.

#Arduino nano pinout prw serial

The microcontroller using in Nano board (ATmega328) offers serial communication (UART TTL). This can be accessible at digital pins like TX, and RX.

#Arduino nano pinout prw software

The Arduino software comprises of a serial monitor to allow easy textual information to transmit and receive from the board. The TX & RX LEDs on the Nano board will blink whenever information is being sent out through the FTDI & USB link in the direction of the computer. The library-like SoftwareSerial allows serial communication on any of the digital pins on the board. The microcontroller also supports SPI & I2C (TWI) communication. The programming of an Arduino nano can be done using the Arduino software. Click the Tools option and select the nano board. Microcontroller ATmega328 over the Nano board comes with preprogrammed with a boot loader.

This boot loader lets to upload new code without using an exterior hardware programmer. The communication of this can be done with the STK500 protocol. Here the boot loader can also be avoided & the microcontroller program can be done using the header of in-circuit serial programming or ICSP with an Arduino ISP. These boards are used to build Arduino Nano projects by reading inputs of a sensor, a button, or a finger and gives an output by turning motor or LED ON, or and some of the applications are listed below.
