Go to the directory where you have downloaded the. If you’re using Arduino IDE 2, you may need to restart it for the library to be available. You will be prompted to select the library you want to add. In the menu bar, go to Sketch > Include Library > Add. The Library Manager looks slightly different depending on what version of the IDE you are using. The latest version is selected by default. When you’ve found a library you want to install, click Install. You can review the description and author. This will usually take you to a reference page or repository for the libraryįind a library you want to install. To find more information about the library, click More info. The results are listed alphabetically, so you may need to scroll down the list. IDE 1.x also has options to filter by Type and Topic.įind the library in the search results.

In IDE 2, you can also click on the button in the sidebar.įilter the available libraries by typing something (such as a library name) in the text field above the listed libraries.

In the menu bar, select Tools > Manage Libraries….

Learn how to add libraries to Arduino IDE. The library's source code will either be found there or else in the src subfolder.Libraries are a collection of code that provide extra functionality for use in sketches, for example when working with hardware or manipulating data.

You can now navigate up a couple of folder levels to get to the library root folder.

This will open the example sketch's folder under the examples subfolder of the library folder.

Select Sketch > Show Sketch Folder from the Arduino IDE's menus.

Open any example sketch from the library you want to find.

Select File > Examples from the Arduino IDE's menus.

This isn't apparent to the user because the libraries have a standardized API. So the Wire library that is used when compiling for the Uno is completely different from the one used when compiling for the Nano 33 IoT, and so on. Each boards platform has its own version of the Wire library. Note that you might have multiple versions of a library installed on your computer and the active version may depend on which board you compile for.

Select the board you are interested in from from the Arduino IDE's Tools > Board menu.

Hi I'll share a technique you can use to find the location of most any library.
