Click Sketch > Verify / Compile to make sure the code is properly in there. Save the file and then attach the Arduino to your computer with the USB cable. Click File > Upload.

That provides a professional development environment, at least. The code base for the Arduino is another frustration. Bluntly, the use of setup() and loop() with main() being hidden really bugs me.

Arduino users and enthusiasts may be interested in some new tools created by the official Arduino team, to make checking your code as easy as possible.
