How to add ZIP library to Arduino IDE

What is a library?

A library is a collection of related pieces of code that have been compiled and stored together in a single file. That file can be linked with your code to give you access to the code in the library.

How to add library?

At first you need to download the ZIP file of the library. Here am using the zip file of ESP8266 WiFi library.

Now let's open the Arduino IDE

Next go to sketch > Include library > Add zip file

Then a window like this will appear >>>>

From that window select the zip file of the library to be added. In my case the zip file is in downloads folder. Then select the zip file and click open.

After that you can see a message that "Your library is successfully added.

To check weather the library is added or not you can go to sketch > Include library >From the drop down list you can see the name of the newly added library
