The Arduino UNO is an open-source microcontroller board based on the Microchip ATmega328P microcontroller and developed by Arduino.cc.[2][3] The board is equipped with sets of digital and analog input/output (I/O) pins that may be interfaced to various expansion boards (shields) and other circuits.[1] The board has 14 digital I/O pins (six capable of PWM output), 6 analog I/O pins, and is programmable with the Arduino IDE (Integrated Development Environment), via a type B USB cable.[4] It can be powered by the USB cable or by an external 9-volt battery, though it accepts voltages between 7 and 20 volts. It is similar to the Arduino Nano and Leonardo.[5][6] The hardware reference design is distributed under a Creative Commons Attribution Share-Alike 2.5 license and is available on the Arduino website. Layout and production files for some versions of the hardware are also available.
The word "UNO" means "one" in Italian and was chosen to mark the initial release of Arduino Software.[1] The UNO board is the first in a series of USB-based Arduino boards;[3] it and version 1.0 of the Arduino IDE were the reference versions of Arduino, which have now evolved to newer releases.[4] The ATmega328 on the board comes preprogrammed with a bootloader that allows uploading new code to it without the use of an external hardware programmer.[3]
While the UNO communicates using the original STK500 protocol:, [1] it differs from all preceding boards in that it does not use the FDDI USB-to-serial driver chip. Instead, it uses the Atmega16U2 (Atmega8U2 up to version R2) programmed as a USB-to-serial converter.[7]
Arduino UNO is a low-cost, flexible, and easy-to-use programmable open-source microcontroller board that can be integrated into a variety of electronic projects. This board can be interfaced with other Arduino boards, Arduino shields, Raspberry Pi boards and can control relays, LEDs, servos, and motors as an output.

Arduino is the advanced form of microcontrollers that are easy to interface with different devices and capable of doing almost every assigned task. Since Arduino is a hardware and software-based platform, programming the microcontrollers has also been made easy using the Arduino IDE.
There are various types of Arduino boards present in the market that includes Arduino UNO, Red Board, Lily Pad Arduino, Arduino Mega, Arduino Leonardo. All these Arduino boards are different in specifications, features and uses and are used in different type of electronics project.
ARDUINO Means Advanced IC. It is better than Microcontroller.
IC Means INTEGRATED Circuit.
Arduino likes PCB.
PCB Means PRINTED CIRCUIT BOARD
THERE ARE TYPES OF ARDUINO.
