Open the Arduino Reference

Still have questions?  Try the Arduino Language Reference.  It’s a set of pages with links you can follow to learn more about setup, loop, print, println, delay, and lots of other functions you can use in your sketches.

  • If you are using the Arduino software, Click Help and Select Reference. 

Opening the Arduino Help > Reference Menu

If you are using Codebender, go to https://www.arduino.cc/en/Reference/HomePage.

  • Try looking up whichever term you might have a question about.  You’ll find setup, loop, and delay on the main reference page. 
  • If you’re looking for links to print or println, you’ll have to find and follow the Serial link first.
