Arduino is a fantastic platform for getting started with electronics and building interactive projects. It consists of two main parts: hardware and software. The Arduino hardware design and software are open-source. This has led to a large and active community of Arduino users who share ideas, projects, and code.
There are many different Arduino boards available, each with different features and capabilities. The Arduino Uno is a popular choice for beginners because it is relatively inexpensive and easy to use. Also it is compatible with a wide variety of third-party add-on boards, or "shields," that can provide additional functionality.
Arduino IDE (Integrated Development Environment) plays the important role in coding and programming the Arduino boards. The software is designed to be easy to learn, even for people with no prior coding experience and its free! to download and use.
