Arduino Arduino Nano User manual

Getting Started with the Arduino
Nano
The Arduino Nano is a small, complete, and breadboard-friendly board based on the
ATmega328P; offers the same connectivity and specs of the UNO board in a smaller form
factor.
The Arduino Nano is programmed using the Arduino Software (IDE), our Integrated
Development Environment common to all our boards and running both online and offline.
For more information on how to get started with the Arduino Software visit the Getting
Started page.

Use your Arduino Nano on the Arduino Web IDE
All Arduino and Genuino boards, including this one, work out-of-the-box on the Arduino
Web Editor, no need to install anything.
The Arduino Web Editor is hosted online, therefore it will always be up-to-date with the
latest features and support for all boards. Follow this simple guide to start coding on the
browser and upload your sketches onto your board.
Use your Arduino Nano on the Arduino Desktop
IDE
If you want to program your Arduino Nano while offline you need to install the Arduino
Desktop IDE To connect the Arduino Nano to your computer, you'll need a Mini-B USB
cable. This also provides power to the board, as indicated by the blue LED (which is on the
bottom of the Arduino Nano 2.x and the top of the Arduino Nano 3.0).
Open your first sketch
Open the LED blink example sketch: File > Examples >01.Basics > Blink.

Select your board type and port
You'll need to select the entry in the Tools > Board menu that corresponds to your Nano
board.
NOTE: We have updated the NANO board with a fresh bootloader. Boards sold from us from
January 2018 have this new bootloader, while boards manufactured before that date have the
old bootloader. First, make sure you have the Arduino AVR Core 1.16.21 or later looking at
the Board Manager. Then, to program the NEW Arduino NANO boards you need to chose
Processor > "ATmega328P". To program old boards you need to choose Processor >
"ATmega328P (Old Bootloader)". If you get an error while uploading or you are not sure
which bootloader you have, try each type of processor 328P until your board gets properly
programmed.

Upload and Run your first Sketch
To upload the sketch to the Arduino Nano, click the Upload button in the upper left to load
and run the sketch on your board:
Wait a few seconds - you should see the RX and TX leds on the board flashing. If the upload
is successful, the message "Done uploading." will appear in the status bar.

Learn more on the Desktop IDE
See this tutorial for a generic guide on the Arduino IDE with a few more infos on the
Preferences, the Board Manager, and the Library Manager.
Tutorials
Now that you have set up and programmed your Arduino Nano board, you may find
inspiration in our Project Hub tutorial platform.
