it features the Atmega8U2 microcontroller chip programmed as a USB-to-serial converter. The Arduino Uno does not use the FTDI USB-to-serial driver chip. You need to simply connect it to a computer with a USB cable for programming and power it with a AC-to-DC adapter or battery to get started to run. All the necessary stuff required to the microcontroller. Also it has a USB connection, an ICSP header, power jack, and a reset button. The Uno has a 16 MHz crystal oscillator which is the heart of the board. You should also read various Arduino boards It is having 14 digital input/output pins, out of which 6 can be used as PWM output and 6 analog inputs. The Arduino Uno board is small and handy approximately 7cm long and 5cm wide. It is simple ideal for hobbyists as well as professionals. ATmega328p is the microcontroller used in Arduino Uno. The Arduino Uno is an open source microcontroller based development board.
In this article I am going to talk about Arduino Uno it’s features and arduino uno pin out, Let’s start… The Arduino Uno board:
