The Arduino environment can be extended through the use of libraries, just like most programming platforms. Libraries provide extra functionality for use in sketches, e.g. Working with hardware or manipulating data. To use a library in a sketch, select it from Sketch Import Library.

I'm confused why you say you 'can't download them'. All of the built-in libraries are already built-in to the Application Bundle. Libraries that aren't included, are downloadable. In previous version of the Arduino IDE, all libraries were stored together deep within the contents folder of the Arduino application. However, in newer versions of the IDE, libraries added through the Library Manger can be found in a folder named ' libraries ' found in your Arduino Sketchbook folder.

Introduction: Make Your Own Arduino Library

View this project on my website!

Arduino is pretty heavily based on C++ (a computer programming language). This language relies upon things called headers, functions,and libraries. These things actually carry over to Arduino too - libraries are included at the top of your code and are used in order to simplify your project code:

In this project I will demonstrate how to make your own Library.

Teacher Notes

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: Software

There is plenty of specialized software you can use for this, but your basic text editor like Notepad should work.

*You could also try something like Notepad++ or VSCode

Step 2: Arduino Code

This is a basic Blink sketch to toggle the on-board LED:

This code isn't very complicated, and it generally wouldn't need a library. However, for the sake of demonstration, we will make one anyway.

Step 3: Make a Library

1. Locate your 'libraries' folder. (Arduino > libraries)
2. Make a new folder entitled 'MyLibrary' - but leave out the quotation marks
3. Within the folder you just made, create a new .txt documents called 'BlinkLED'
4. Open the file in your editor
5. Save the file with a .h extension (file > save as)
6. Repeat (same title) with a .cpp extension

Code to go in the .h file:

Code to go in the .cpp file:

Now save both files and exit.

The package also includes callback functions for StatET. For example: packageDescription('rj')Encoding: UTF-8Package: rjVersion: 2.1.0-13Title: RJ - R Package for high-level Java-R library RJAuthor: Stephan Wahlbrink, Tobias Verbeke, low-level R binding based on the JRI library by Simon UrbanekMaintainer: Stephan Wahlbrink Depends: R (= 2.11.0)Suggests: rj.gdSystemRequirements: javaDescription: Server implementation and R functions for the high-level Java-R library RJ. Mac set path variable. You may use the function to find the paths to one or more packages.Example (finding the path of the R library rj): find.package('rj')1 'nas/users/dernoncourt/Documents/dernoncourt/R/win-library/3.4/rj'Alternatively you may use packageDescription. It is shipped with an adapted version of the JRI library.

Step 4: Include Library

Close the Arduino IDE and reopen it. Go to Sketch > Include Library and scroll down to 'Contributed Libraries.' You should see one called MyLibrary. Click on it, and you should see:

If the above code appears, then you're good to go. Just upload the rest of the code.

Now, instead of having to declare the pin an output and tell it to turn on and off, we just use our library. All you have to do is tell it which pin you want to blink and how often to blink it.

Step 5: Going Further

If you want your library to do more than blink an LED, all you have to do is edit the two files from before. If you are interested in making more complicated libraries, it may help you to learn more about C++.

Now that all the SD card functionality appears to be working, the program below allows you to view the files on an SD card over the Ethernet interface and download any file you wish.

The program will provide a directory listing of the SD card to a web page. If a directory is clicked, the web page will show the contents of the subdirectory. If a file is clicked, the file will be sent to your computer. If you want to go back up the directory tree, use the browser back button.

The library which provides the WIZ5500 Ethernet functionality is called Ethernet2. The Adafruit version of Ethernet2 has been maintained and should be used instead of the Ethernet2 library available in the Arduino Library Manager. You can get the library code on GitHub at https://github.com/adafruit/Ethernet2.

It is suggested that you put the Ethernet2 code from the Adafruit GitHub repository into your Arduino sketch folder, in the libraries subdirectory, in a subdirectory called Ethernet2.

For the source code below, you should review the following in the code:

• Byte array mac[] is set to a generic MAC address - if you have another device on your home network with the same address, change things a bit. Each value is an 8 bit value in hexadecimal (from 00 to FF).
• Byte array ip[] is the Internet Protocol (IP) address of an unused device on your home network. Having the Ethernet board way up at 177 (decimal) is fairly safe - if you know networking and this will not work, if you have your network on a network other than 192.168.1.xxx (say at 192.168.0.xxx or 10.0.0.xxx) change those also. You can find information like this from your Internet router.
• If you want to use DHCP to get an address from your router, uncomment the version of the Ethernet.begin call with only the mac address. It may be more difficult to get the address and the address might change is the router gives out a new address. So the default is a fixed address.
