What is Arduino?
Arduino is an open-source electronics platform based on
easy-to-use hardware and software. Arduino
boards are able to read inputs - light on a sensor, a finger on
a button, or a Twitter message - and turn it into an output - activating a
motor, turning on an LED, publishing something online. You can tell your board
what to do by sending a set of instructions to the microcontroller on the
board. To do so you use the Arduino
programming language (based on Wiring),
and the Arduino
Software (IDE), based on Processing.
It was in
the year 2005 that the first ever Arduino board was born in the classrooms of
the Interactive Design Institute in Ivrea, Italy. Well, if you are not very
familiar with the term, an Arduino is an
Open Source microcontroller based development board that has opened the
doors of electronics to a number of designers and creative engineers.
It was in the Interactive Design Institute that a
hardware thesis was contributed for a wiring design by a Colombian student
named Hernando Barragan. The title of the thesis was “Arduino–La rivoluzione
dell’open hardware” (“Arduino – The Revolution of Open Hardware”). Yes, it
sounded a little different from the usual thesis but none would have imagined
that it would carve a niche in the field of electronics.

microcontroller

ARDUINO UNO R3 (Blue)
This is
the new Arduino Uno R3 made in Italy with box. In addition to all the features
of the previous board, the Uno now uses an ATmega16U2 instead of the 8U2 found
on the Uno (or the FTDI found on previous generations). This allows for faster
transfer rates and more memory. No drivers needed for Linux or Mac (inf file
for Windows is needed and included in the Arduino IDE), and the ability to have
the Uno show up as a keyboard, mouse, joystick, etc. The Uno R3 also adds SDA
and SCL pins next to the AREF. In addition, there are two new pins placed near
the RESET pin. One is the IOREF that allow the shields to adapt to the voltage
provided from the board. The other is a not connected and is reserved for
future purposes. The Uno R3 works with all existing shields but can adapt to
new shields which use these additional pins. Arduino
is an
open-source physical computing platform based on a simple i/o board and a
development environment that implements theProcessing/Wiring language. Arduino
can be used to develop stand-alone interactive objects or can be connected to
software on your computer (e.g. Flash, Processing, MaxMSP). The open-source IDE
can be downloaded for free (currently for Mac OS X, Windows, and Linux).

Arduino Uno R3 Board
The Arduino Uno R3 is
a open source microcontroller board based on the ATmega328 chip. This
Board has 14 digital input/output pins, 6 analog input
pins, Onboard 16 MHz ceramic resonator, Port for USB connection,
Onboard DC power jack, An ICSP header and a microcontroller reset button. It
contains everything needed to support the microcontroller. Using the board is
also very easy, simply connect it to a computer with a USB cable or power it
with DC adapter or battery to get started.
The Uno differs from all preceding boards in that it does
not use the FTDI USB-to-serial driver chip. Instead, it features the
Atmega16U2Atmega8U2 up to version R2) programmed as a USB-to-serial converter.
While the Arduino UNO can be powered via the USB connection or with an external
power supply, the power source is selected automatically.
External (non-USB) power can come either from an AC-to-DC
adapter (wall-wart) or battery. The adapter can be connected by plugging a
2.1mm center-positive plug into the board's power jack. Also leads from a battery
can be inserted in the Gnd and Vin pin headers of the Power connector. The
board can operate on an external supply of 6 to 20 volts. If supplied with less
than 7V, however, the 5V pin may supply less than five volts and the board may
be unstable. If using more than 12V, the voltage regulator may overheat and
damage the board. The recommended range is 5v to 12v for Arduino Uno.
