Folder Location and Installation of Arduino Libraries
Where is Arduino Libraries Folder?
When you create a library for your Arduino project, you can share it with other people on the Internet. These libraries are called core or standard libraries.
The libraries are installed in a special folder within the sketchbook directory of the Arduino IDE software. Libraries in this folder are available when you select Sketch > Include Library.
Core libraries
Libraries are collections of code that can be added to an Arduino program to add extra functionality. They usually include support for external modules and boards, as well as commonly used functionalities. Ideally, they should also contain examples that demonstrate how to use the library. This will make it easier for others to understand how to use the library. Libraries are typically stored in the
The libraries folder can be found in the
Once the zip file is extracted, the folder and files should be copied into the libraries directory. Then restart the Arduino IDE, and if the library was installed correctly, you should see it under the Sketch -> Include Library menu.
Third-party libraries
The Arduino libraries folder contains a variety of third-party software packages. These libraries offer extra functionality for your programs, such as controling an LED matrix or reading an encoder. They can also add support for certain boards or common functionalities. These libraries are available for download from the Internet and typically come in the form of a zip file.
You can install these libraries in the Arduino IDE by using the Library Manager or the Sketch > Include Library menu. You will need to restart the IDE after installing each library. This is necessary because the IDE creates a database of available libraries internally, and it needs to restart to update this database.
Once you have installed a new library, you can export it into an archive and share it with others. The library folder should be placed in the Arduino/libraries/ directory on your computer. To do so, go to the Sketch > Include Library menu and select the option to add a.ZIP Library.
Installing libraries from the source code
Before you install a library from the source code, make sure to check that it is compatible with your Arduino board. This will prevent conflicts with existing libraries and will also avoid polluting the Arduino IDE’s /usr/local folder where it stores 3rd party libraries (the “libraries” folder).
You can find many core and third-party libraries online. Just download the zipped version and extract it. Once the library has been installed, you can find it in the Sketch > Include Library menu.
User-installed libraries are stored in a separate folder from the main Arduino IDE software, so they can be used with any future versions of the IDE. They are also portable between different computers. Libraries are files written in C or C++ that give your sketches extra functionality. Typically, they consist of a header file (.h) and a source file (.cpp). When you use a library in a project, the header file is imported to the project’s source code. The resulting code is then compiled to generate the binary for your board.
Delete libraries
There are several ways to delete libraries from the Arduino IDE, including using the Library Manager (requires IDE 2.0) or manually. However, you should only use the latter method if you are unsure about whether or not you need the library in your sketch.
The first step is to find the location of your sketchbook folder. This can be found by clicking “File > Preferences” and selecting the Sketchbook Location tab. The sketchbook folder is where the IDE will look for user installed libraries.
Once you have found the sketchbook folder, you can then find the library you want to remove. To do so, hover over the INSTALLED label next to the library name. When the INSTALLED button changes to UNINSTALL, click it. This method is simple and works for all types of libraries and versions of the IDE. It also works well for removing multiple libraries at once. It is a good idea to back up the libraries before deleting them in case you need them again.
