USART: The board supports USART serial communication that carries two pins i.e. These pins are used in case of emergency. ![]() These pins are used to reset the controller internally through software.Įxternal Interrupts: Pin 2 and 3 are used to trigger external interrupts. Reset: Two reset pins are integrated on the board. GND: Two ground pins are available on the board. VIN: This is an input voltage to the Arduino board when using an external power source (6-12V).ģ.3V: It is a minimum voltage produced by the voltage regulator on the board.ĥV: Regulated power supply used to power up the controller and other components on board.ĪREF: It is an Analog Reference that is applied to the unit as a reference voltage from an external power supply. LED: The unit comes with a built-in LED connected to pin 13 on the board. In this section, we’ll cover the Arduino Nano Pinout, we will discuss pin description of each pin integrated on the board.ĭigital Pins: There are 14 digital pins on board which is used to connect external component.Īnalog Pins: 6 analog pins on board that is used to measure voltage in a range from 0 to 5V. The following figure shows the pinout diagram of the Arduino Nano board. The Nano board is almost similar to the UNO board with the former smaller in size with no DC power jack. Similarly, the EEPROM is 512KB and 1KB, and SRAM is 1KB and 2KB for Atmega168 and Atmega328 respectively. The flash memory is used to store the program and the flash memory of Atmega168 is 16KB (of which 2KB is used for the Bootloader) and the flash memory of Atmega328 is 32KB. Plus, this device is bread-board friendly in nature means you can connect this unit with breadboards and make a range of electronic projects. you cannot power the board from an external power supply. And there is no DC power jack included in this unit i.e. The board supports a USB interface and it uses a mini USB port, unlike most Arduino boards that use the standard USB port. The clock frequency of this unit is 16MHz which is used to generate a clock of a certain frequency using constant voltage. Like other Arduino boards, the operating voltage of this device is 5V, while input voltage ranges between 6V to 20V while the recommended input voltage ranges from 7V to 12V. This unit features 14 digital pins which you can use to connect with external components, while 6 analog pins of 10-bit resolution each, 2 reset pins, and 6 power pins are integrated on the board. Two versions of this board are available, one is based on ATmega328p, and the other on Atmega168.Īrduino Nano can perform some functions similar to other boards available in the market, however, it is smaller in size and is a right match for projects requiring less memory space and fewer GPIO pins to connect with. Including What is Arduino Nano, Pinout, Pin Description, Programming & Applications.Īrduino Nano is a small, compatible open-source electronic development board based on an 8-bit AVR microcontroller. ![]() In this post, I’ll cover each and everything related to Arduino Nano (696-1667) All you need to learn is coding – to program the board and you’re good to design, develop and modify electronic projects on the go. Everything is combined inside a single package and you can simply plug the device into the computer and start playing with it. These units are a remarkable addition to the electronic industry as they are easy to learn and easy to integrate into a variety of electronic projects. ![]() In this post today, I’ll discuss Arduino Nano in detail.Īrduino boards are introduced for non-tech people who struggle to make heavy electronic circuits with a constant worry to put all wires and components in place. Turns on an LED on for one second, then off for one second, repeatedly.Hi Guys! Hope you’re well today. Open the new sketch File by clicking New. Coding in the Arduino language will control your circuit. Open the Arduino IDE software on your computer. The shorter of the two legs, towards the flat edge of the bulb indicates the negative terminal.Ĭomponents like resistors need to have their terminals bent into 90° angles in order to fit the breadboard sockets properly. Note − To find out the polarity of an LED, look at it closely. Components Requiredįollow the circuit diagram and hook up the components on the breadboard as shown in the image given below. ![]() Establishing this important baseline will give you a solid foundation as we work towards experiments that are more complex. It is as simple as turning a light on and off. To start, we will work on blinking an LED, the Hello World of microcontrollers. LEDs are small, powerful lights that are used in many different applications.
