![]() They operate at 5 V.Įach pin can provide or receive a maximum of 40 mA and has an internal pull-up resistor (disconnected by default) of 20-50 kOhms. 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.Įach of the 14 digital pins on the Nano can be used as an input or output, using pinMode(), digitalWrite(), and digitalRead() functions.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 power source is automatically selected to the highest voltage source. 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 message will be visible in the status bar.16 KB (ATmega168) or 32 KB (ATmega328) of which 2 KB used by bootloaderĥ12 bytes (ATmega168) or 1 KB (ATmega328) The ' Done Uploading' message will appear after the code is successfully uploaded. Within the few seconds after the compile and run of code or sketch, the RX and TX light present on the Arduino board will flash. To upload and run, click on the button present on the top panel of the Arduino display, as shown below: Now, upload and run the written code or sketch.So, we will select the Processor as ATmega328p.Ĭlick on 'Tools' and select Processor, as shown below: The ATmega328p microcontroller is used in the Arduino Nano. Open the code or sketch written in the Arduino software.The steps to get started with Arduino Nano are listed below: We can also use Arduino Web Editor, which allows us to upload sketches and write the code from our web browser (Google Chrome recommended) to any Arduino Board. We can program the Arduino Nano using the Arduino IDE. The flexibility and eco-friendly nature of Nano make it a unique choice to create electronic devices and projects with compact size.The functionality of Nano is similar to the Arduino UNO.We can also connect Arduino Nano to the Wifi.The projects created using Arduino Nano are QR Code Scanner, DIY Arduino Pedometer, etc.The Arduino Nano is used in various applications such as Robotics, Control System, Instrumentation, Automations, and Embedded Systems.The crystal oscillator present in Arduino Nano comes with a frequency of 16MHz.The conversion takes place by varying the width of the pulse. ![]() The 6 PWM pins in Arduino Nano are used to convert the digital signals into the analog signals. There are 6 PWM (Pulse Width Modulation) pins among the 14 digital pins.There are 14 digital pins and 8 analog pins.The total pins in Nano are 22 Input/Output pins.The operating voltage of the Nano board varies from 5V to 12V.The technical specifications of the Arduino Nano board are: The preinstalled flash has a boot loader, which takes the memory of 2Kb. The memory in Arduino Nano is shown in the below image: It also includes 6 Power pins and 2 Reset pins. The Arduino Nano includes an I/O pin set of 14 digital pins and 8 analog pins. The Arduino UNO includes 6 analog pin inputs, 14 digital pins, a USB connector, a power jack, and an ICSP (In-Circuit Serial Programming) header.The Nano is available in PDIP (Plastic Dual - Inline Package), while Arduino UNO is available in TQFP (Plastic Quad Flat Pack).It is considered as the standard board available in the market, which is easy for use for the starters or beginners. The Arduino UNO is also easily available than Nano.We can use Nano instead of UNO because both operate on the microcontroller ATmega328p. The Arduino Nano has a compact size and mini USB cable than the Arduino UNO.What is the difference between Arduino UNO and Nano board? Using the constant voltage, the Arduino Nano is used to produce a clock of a precise frequency. The Arduino Nano is shown below: Why is Arduino Nano used? Thus, we cannot use a battery to apply any external power supply. The mini USB transfers the code from the computer to the Arduino Nano board.ĭrawback: The DC power jack is absent in Nano. The Arduino IDE software must be installed on our respected laptop or desktop. The devices required to start our projects using the Arduino Nano board are Arduino IDE and mini USB. Here, IDE stands for Integrated Development Environment. The Arduino Nano is organized using the Arduino (IDE), which can run on various platforms. It is small in size compared to the UNO board. The Nano board is defined as a sustainable, small, consistent, and flexible microcontroller board. The connectivity is the same as the Arduino UNO board. The Arduino Nano is a small Arduino board based on ATmega328P or ATmega628 Microcontroller.
