Importing Third-Party Libraries - Arduino Sketches: Tools and Techniques for Programming Wizardry - page 387

Now that your library has been imported, you can use it. It becomes available
immediately and is listed in the Import Library menu. This library also adds
an example, available for use immediately in the File Examples menu. Note

that for both the Import Library and the Example menu items, external libraries
are separated from standard libraries.
Now, load the Si1145 example sketch shown here:

➪

1 /***************************************************
2 This is a library for the Si1145 UV/IR/Visible Light Sensor
3
4 Designed specifically to work with the Si1145 sensor in the
5 adafruit shop
6 ----> https://www.adafruit.com/products/1777

8 These sensors use I2C to communicate, 2 pins are required to
9 interface
10 Adafruit invests time and resources providing this open source
code,
