Preparing and Running Your First Program
-
Learn the basics of Arduino programming and watch your device come to life!
The instructions below are based off the Arduino getting started guide.
To create a runnable program, you only need to use two functions:
setup() – Run once at the start
loop() – Run repeatedly
The image on the right shows a program that will make an on-board LED blink.
You can easily upload this program by going to File > Examples > 01.Basics > Blink.
Once that's done, click the arrow
at the top of the IDE to upload the software to the board.

Error Uploading?
The image to the left depicts a common error that is encountered when an incorrect COM port or board is selected. Try changing those features and uploading the software again.
