Run the Arduino IDE by double-clicking the icon with the white on blue infinite logo,
the one that says "Arduino" beside it, on your print screen.
From within the Arduino application (the IDE), use the File -> Open menu option to
load up the "MyDoorOpener.ino" file. From there you can edit the file, save it and
upload it to your Arduino controller.
There you go ...
