#VIRTUAL WIRE LIBRARY ARDUINO DOWNLOAD HOW TO#
You might want to add some comments that better explain how to use your library. (You can find the sketch using the Sketch > Show Sketch Folder command.) If you restart the Arduino environment (this is the last time, I promise) - you'll see a Library-Morse item inside the File > Sketchbook > Examples menu containing your example. Then, move or copy the directory containing the sketch (let's call it SOS) we wrote above into the examples directory. To do this, create an examples directory inside the Morse directory. It's also nice to provide people with an example sketch that uses your library. You'll have to restart the Arduino environment to get it to recognize the new keywords. Classes should be KEYWORD1 and are colored orange functions should be KEYWORD2 and will be brown. The core of the header file consists of a line for each function in the library, wrapped up in a class along with any variables you need:Įach line has the name of the keyword, followed by a tab (not spaces), followed by the kind of keyword. It might seem a bit strange at first, but it will make more sense once you see the source file that goes with it. We'll call our library "Morse", so our header file will be Morse. The header file has definitions for the library: basically a listing of everything that's inside while the source file has the actual code.
You need at least two files for a library: a header file (w/ the extension. Let's start turning the sketch into a library! Finally, there's the call to pinMode ( ) that initializes the pin as an output.
Second, there's the pin variable which the functions use to determine which pin to use. First, of course, we have the dot ( ) and dash ( ) functions that do the actual blinking. The sketch has a few different parts that we'll need to bring into our library.

If you run this sketch, it will flash out the code for SOS (a distress call) on pin 13.
