How to install Arduino Library

Once you are comfortable with the Arduino software, you may want to extend the library to meet your requirement.

Libraries are often distributed as a ZIP file or folder. The name of the folder is the name of the library. Inside the folder will be a .cpp file, a .h file and often a keywords.txt file, examples folder, and other files required by the library.

Take Arduino1.0.5 as example, you can install a library in Arduino IDE. And Do not unzip the downloaded library, leave it as is.

In the Arduino IDE, click Skietch->Import Library. At the top of the drop down list, select the option to "Add Library.

You will be prompted to select the library you would like to add. Find the .zip file's location and open it. Here I select a library named smallePaper .

Return to the Sketch > Import Library menu. You should now see the library at the bottom of the drop-down menu. It is ready to be used in your sketch.

Now the zip file has been installed in your Arduino sketches directory. You can see the location of the library: File->Preferences->Sketchbook location, and can change the location. Generally, we will change it as ….Arduino – 1.0.5\libraries as showing below.
