It includes USB connectivity for easy programming and debugging, supports R3 shields, and is designed with a compact SMD construction for durability and efficient prototyping. ## Description The Arduino Uno is an open-source microcontroller board based on the Microchip ATmega328P microcontroller. The board is equipped with sets of digital and analog input/output pins that may be interfaced with various expansion boards and other circuits. Features of Arduino Uno: The chip on the board plugs straight into your USB port and supports your computer as a virtual serial port. It is easy to find the microcontroller brain which is the ATmega328 chip. It is a 16 MHz clock which is fast enough for most applications and does not speed up the microcontroller. It has 32 KB of flash memory for storing your code. An on-board LED is attached to digital pin 13 to make fast the debugging of code and to make the debug process easy.
