Arduino Nano

The Arduino Nano is a compact, breadboard-friendly microcontroller board based on the ATmega328 (or similar chips), designed for small-scale electronics projects and prototyping. It offers the same core functionality as larger Arduino boards but in a smaller form factor, with digital and analog input/output pins, USB connectivity for programming, and support for a wide range of sensors and components. Its low cost, ease of use, and compatibility with the Arduino IDE make it especially popular among beginners and hobbyists building embedded systems.
