Arduino Libraries Download and Projects they are used in– In this article, I am going to share with you Top Arduino, Nodemcu ESP8266, and ESP32 libraries and their download links along with the projects links they are used in. So far I have worked on more than 600 projects. All these projects were developed only using the libraries that I am about to share with you guys.

The reason I am writing this article is just that my followers on YouTube channel “Electronic Clinic” keep asking for the download links of the libraries. So that’s why I decided to write a complete article explaining each and every library along with the download link and the projects they are used in.

So without any further delay, let’s get started!!!

Arduino IDE and built-in Libraries:

The Arduino IDE itself comes with some built-in libraries which you can find by clicking on the Sketch menu > include library.

Arduino Libraries Download

You will find a long list of the Libraries which are already installed. You simply click on the library and it’s added in the Arduino IDE. But there are situations when you need some other libraries to complete a certain project. Let’s start with the most commonly used Arduino libraries.
