Arduino Nano is a small and compact microcontroller board that is based on the ATmega328P microcontroller. It is similar to the Arduino Uno board in terms of functionality and programming, but it is smaller in size and has a different form factor. The Arduino Nano board has 14 digital I/O pins and 8 analog input pins, which can be used to interface with a wide range of sensors, actuators, and other electronic components. It also has a USB interface that can be used to program the board and communicate with a computer, and it can be powered either through the USB cable or an external power supply. The board is compatible with the Arduino Integrated Development Environment (IDE) software and can be programmed using C or C programming languages. It is often used in projects where size is a constraint, such as wearable devices, small robots, and portable electronic projects. The Arduino Nano board is a popular choice among hobbyists and makers due to its small size, low power consumption, and ease of use. Its compact form factor makes it ideal for use in small-scale projects and prototypes. It can also be used as a module in larger systems, where space is at a premium.
