Arduino Uno Pin Diagram, Specifications, Pin Configuration & Programming
The Arduino UNO R3 is frequently used microcontroller board in the family of an Arduino. This is the latest third version of an Arduino board and released in the year The main advantage of this board is if we make a mistake we can change the microcontroller on the board. ARDUINO UNO Revision 3 BOARD The Arduino Uno is one of the most common and widely used Arduino processor boards. There are a wide variety of shields (plug in boards adding functionality). It is relatively inexpensive (about $25 - $35). The latest version as of this writing (3/) is Revision 3 (r3). X bit US Galileo Datasheet arduino uno r3: arduino uno r3. Abstract: arduino uno uno r3 Text: software pin-compatible with Arduino shields designed for the Uno R3. Digital pins 0 to 13 (and the, (0 and 1), are all in the same locations as on the Arduino Uno R3. This is also known as the Arduino.

Used for TWI communication. To provide reference voltage for input voltage. Operating Voltage. Recommended Input Arduino uno r3 datasheet pdf download. Input Voltage Limits. Analog Input Pins. DC Current on 3. Flash Memory. Frequency Clock Speed. Arduino Uno is a microcontroller board based on 8-bit ATmegaP arduino uno r3 datasheet pdf download. Along with ATmegaP, it consists other components such as crystal oscillator, serial communication, voltage regulator, etc.
Each pin operate at 5V and can provide or receive a maximum of 40mA current, and has an internal pull-up resistor of KOhms which are disconnected by default. Out of these 14 pins, some pins have specific functions as listed below:. Along with 14 Digital pins, there are 6 analog input pins, each of which provide 10 bits of resolution, arduino uno r3 datasheet pdf download, i.
They measure from 0 to 5 volts but this limit can be increased by using AREF pin with analog Reference function. Arduino can be used to communicate with a computer, another Arduino board or other microcontrollers. An ATmega16U2 on the board channels this serial communication over USB and appears as a virtual com port to software on the computer.
However, on Windows, a. The Arduino software includes a serial monitor which allows simple textual data to be sent to and from the Arduino board.
A SoftwareSerial library allows for serial communication on any of the Uno's digital pins. The Arduino software includes a Wire library to simplify use of the I2C bus. When ATmega chip is used in place of Arduino Uno, or vice versa, the image below shows the pin mapping between the two. Download it here.
Arduino Uno is programmed using Arduino programming language based on Wiring. Below is the example code for blinking:.
