Description
The Arduino Nano is a small, flexible, and versatile microcontroller board compatible with the Arduino IDE. It provides the same functionality as the Arduino Uno but in a smaller footprint, ideal for embedded projects and breadboard integration. Equipped with 14 digital I/O pins, 8 analog inputs, and a USB interface for programming, the Nano is widely used in hobbyist projects, wearable electronics, IoT prototypes, and automation systems.
