Arduino Basics and Functions

Arduino is an open-source microcontroller platform that allows users to create digital hardware products. Originating in Italy in 2005, it has sold over 10 million units worldwide. The most popular model, the Uno, features a microcontroller, pins for circuit construction, and a USB port for code uploads. Arduino programs, called sketches, are written in a simple language with two main functions: setup and loop. Users can start by obtaining a board, downloading the IDE, and connecting via USB. The platform supports various projects, from blinking LEDs to complex circuits using breadboards and components. Arduino is ideal for building IoT products, robots, and more.
