Arduino Uno is a
development board which is used all around the globe. Arduino Uno is
based on ATmega328p microcontroller developed in Italy. Arduino has
various types like Arduino Uno, mega, nano, pro mini, learnado etc. In
this blog, we will be focussing on Arduino Uno. It has digital and analog input/output (I/O) pins that may be interfaced with different
shields and circuits. It has 14 digital pins and 6 analog pins.
The Arduino board is programmed by Arduino ide
(integrated development environment) software via type B cable. The
Arduino ide software can be downloaded from arduino.cc website which is
around 97 MB.
To select the board type and port go to tools a drop-down
menu will appear click on boards and select Arduino Uno after that go
below and select port option choose the only port available and you're
done with setting up the software. Arduino is powered by cable or it can
be done with a 9-volt battery. The language used to program Arduino is
c. Arduino Uno Is most commonly used because it is user-friendly. Most
beginners choose Arduino Uno as a first development board as it is easy
to learn. Arduino Uno was the first development board in the series with
a USB. In Italian Uno means one.
So, many Chinese
companies started making clone version of original Arduino which works
perfectly as genuine Arduino, as these clones were cheap and worked fine
most people started preferring clones version of Arduino.
