Getting started with Arduino Nano

Install the Arduino IDE (or use Arduino Cloud Editor) and add USB drivers if your OS needs them.

Connect the Nano with a data USB cable. In Tools, choose the Nano board and the correct COM/serial port.

Open File → Examples → 01.Basics → Blink, then Upload. The onboard LED should blink once a second.

If upload fails, try the old bootloader option or a different USB cable — charge-only cables are a common issue.
