If you are beginner to Arduino you must be confused of selecting the right board for your need. As I strongly suggest Arduino Uno R3 for every beginner to the expert, here I bring some important fact about the board. So read on and get more and more knowledge about Arduino on the way to building your own project.
Why to turn Arduino Uno?
Arduino Uno is the most used board in the Arduino family which is a microcontroller board based on the ATmega328. This is one of latest and smartest in the series of USB Arduino boards. In fact the word “Uno” stands for the the release of Arduino 1.0 standing with the mean of “one” in Italian. This board can be easily set up and mange even at the infant stage of knowledge. In the other side it is with a reasonable price tag and allow to change ATmega 328p microcontroller at any mess in the board run for few bucks. In that way turning to Arduino Uno is easier in the way to your project.
Arduino Uno Features
Operating Voltage as 5V
Input Voltage 6-20V
Input Voltage (recommended) 7-12V
Digital I/O Pins: 14 ( 6 that provide PWM output)
DC Current per I/O Pin: 40 mA
Analog Input Pins: 6
DC Current for 3.3V Pin: 50 mA
Flash Memory counts 32 KB (0.5 KB occupied for the bootloader)
SRAM: 2 KB (ATmega328)
Clock Speed 16 MHz
EEPROM: 1 KB (ATmega328)
Arduino Uno R3- The Third Revision
In 2011 Arduino Uno R3 marked its official release as the third revision of Uno boards. And it required Arduino 1.0 driver install in some computers specially when you use R3 in a new computer. And as to the tested and confirmed information Arduino Uno R3 supports and can be programmed in older versions of the Arduino IDE. And this is strongly recommended in the cases of electronic projects as you can get maximum benefit with a less effort on the project. In fact Arduino Uno R3 is now with SDA and SCL pins added next to the AREF and also with new two pins located near the RESET. In that way Arduino Uno R3 helps current available shields while with the hope of adapting to new shields too.
Arduino microcontroller connecting via USB
Upgraded to ATMEGA16U2
Appears as the Revision 3 of Uno boards
Availability of number of “Shields” with facility to adapt new
I/O pins as analog, digital, PWM and more
Designed for hobbyists, roboticists, artists, designers and so on
Based on the ATmega328 (removable DIP IC)
Arduino Uno R3 became popular because of its useful features. Addressing the hardship factors Arduino Uno comes to the user supporting for a profitable output. So make your project too run with Arduino Uno R3 the third successful revision of Arduino Uno boards. In memory, USB interface, clock speed, input/output voltage, Pins, communication, programming and in every side Arduino Uno R3 is supportive. So take your chance too with this supportive board and share your comments about your time with Arduino Uno and R3.
