A library is a collection of pre-written code or functions that extend the capabilities of the Arduino IDE. Libraries provide ready-to-use code for various functionalities, allowing you to save time and effort in coding complex features.
There are two main ways to install libraries:
Many libraries are available directly through the Arduino Library Manager. You can access the Library Manager by following these steps:
In the Library Manager, you can search for the desired library by name or browse through different categories.
