The built-in libraries and some of these additional libraries are listed in the reference. To use the additional libraries, you will need to install them. How to Install a Library Using the Library Manager. To install a new library into your Arduino IDE you can use the. Once you are comfortable with the Arduino software and using the built-in functions, you may want to extend the ability of your Arduino with additional libraries. What are Libraries? Libraries are a collection of code that makes it easy for you to connect to a sensor, display, module, etc.

Type repairHomePermissions in the Terminal window, then press Return. The Repair Home app opens. When you see the macOS Utilities window, choose Utilities Terminal from the menu bar. Enter the requested password to continue.

Follow these steps to install a library in Mac OSX.

Close the Arduino IDE

First make sure that all instances of the Arduino IDE are closed. The IDE only scans for libraries at startup. It will not see your new library as long as any instance of the IDE is open!

Download the Zip File Make sure to select a released version of the library. Some library repositories are still in development, and may contain unreleased or untested code. The 'Releases' button takes you to the tested and released versions. Click the 'Releases' button on the Github repository page to find the released version of the library. Then download the zip file.

Find it in the Downloads Folder OSX will automatically open the zip file there.

Drag it to your Libraries Folder Open your sketchbook Libraries folder and drag the master folder from Downloads into it.

Give it a Legal Name The IDE will not recognize folders with dashes in the name. So you must rename the Github Master Folder. Underscores are OK!

Re-start the IDE Restart the Arduino IDE and verify that the library appears in the File->Examples menu. Load one of the library examples to test.

Verify that it Compiles Click the check-mark icon in the upper left and verify that the example sketch compiles without errors.

These instructions describe an installation of the Arduino Software and drivers for an Arduino Uno on Mac OS X Lion, but will work the same for Leopard, Snow Leopard and Mountain Lion. Previous operating systems may require you to search the web for your specific situation.

Follow these steps to install the Arduino software on your Mac:

1Go to the Arduino downloads page and click the Mac OS X link to download a .zip file containing a copy of the Arduino application for Mac OS X.

Currently, the file is 71.1MB. That’s quite a large file, so it may take a while to download. After you’ve finished downloading, double-click the file to the Arduino application and place it in your Applications folder.

2Plug the square end of the USB cable into the Arduino and the flat end into an available port on your Mac to connect the Arduino to your computer.

As soon as the board is connected, a dialog box appears, showing the message A new network interface has been detected.

3Click Network Preferences, and in the window that appears, click Apply.

Where Are Arduino Libraries On Mac Pro

Note that your Arduino is displayed in the list on the left side of this window as Not Configured, but don’t worry, the software is installed and your Arduino board will work.

4Close the Network Preferences window.

Arduino Library Locations

To launch the Arduino application, go to your Applications folder, locate the Arduino application, drag it to the Dock, and then click the Arduino icon to open the Arduino application. If you prefer, you can also drag the application to the desktop to create an alias there instead.
