The Arduino website serves as a central reference for Arduino projects and programming.
All built-in examples have their own page that provides instructions and information on how they work.
Every function, variable type, and structural statement has its own page with examples and instructions on how to use it.
These examples are based on the built-in example Blink.
Uploading Blink Example
- Open Arduino IDE
- File > Examples > 01.Basics > Blink
- Select port (USB), board (Nano), and processor (328 or 168)
- Upload to Arduino

Uno vs. Nano
All the examples on the website are for Arduino Uno, but you will be using the Arduino Nano (they are very similar).
When using diagrams for the Uno, make sure to use the same pins on the Nano and you should see the same effect.
