Each pin can provide or receive 20 mA as the recommended operating condition and has an internal pull-up resistor (disconnected by default) of 20-50K ohm.

  • Reset: Typically used to add a reset button to shields that block the one on the board.Įach of the 14 digital pins and 6 analog pins on the Uno can be used as an input or output, under software control (using pinMode(), digitalWrite(), and digitalRead() functions).
  • A properly configured shield can read the IOREF pin voltage and select the appropriate power source, or enable voltage translators on the outputs to work with the 5V or 3.3V.
  • IOREF: This pin on the Arduino/Genuino board provides the voltage reference with which the microcontroller operates.
  • 3V3: A 3.3 volt supply generated by the on-board regulator.
  • Supplying voltage via the 5V or 3.3V pins bypasses the regulator, and can damage the board. The board can be supplied with power either from the DC power jack (7 – 20V), the USB connector (5V), or the VIN pin of the board (7-20V).

  • 5V: This pin outputs a regulated 5V from the regulator on the board.
  • You can supply voltage through this pin, or, if supplying voltage via the power jack, access it through this pin.
  • VIN: The input voltage to the Arduino/Genuino board when it is using an external power source (as opposed to 5 volts from the USB connection or other regulated power source).
  • When the pin is high value, the LED is on, when the pin is low, it is off.
  • LED: There is a built-in LED driven by digital pin 13.
  • You can tinker with your Uno without worrying too much about doing something wrong, worst case scenario you can replace the chip for a few dollars and start over again. It contains everything needed to support the microcontroller simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header and a reset button. Main FeaturesĪrduino Uno is a microcontroller board based on the ATmega328P.

    Instead, it uses the Atmega16U2 (Atmega8U2 up to version R2) programmed as a USB-to-serial converter.

    While the Uno communicates using the original STK500 protocol, it differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip.

    The ATmega328 on the board comes preprogrammed with a bootloader that allows uploading new code to it without the use of an external hardware programmer. The Uno board is the first in a series of USB-based Arduino boards it and version 1.0 of the Arduino IDE were the reference versions of Arduino, which have now evolved to newer releases. The word “uno” means “one” in Italian and was chosen to mark the initial release of Arduino Software. Layout and production files for some versions of the hardware are also available.

    The hardware reference design is distributed under a Creative Commons Attribution Share-Alike 2.5 license and is available on the Arduino website. It is similar to the Arduino Nano and Leonardo. It can be powered by the USB cable or by an external 9-volt battery, though it accepts voltages between 7 and 20 volts. The board has 14 digital I/O pins (six capable of PWM output), 6 analog I/O pins, and is programmable with the Arduino IDE (Integrated Development Environment), via a type B USB cable. The board is equipped with sets of digital and analog input/output (I/O) pins that may be interfaced to various expansion boards (shields) and other circuits. The Arduino Uno is an open-source microcontroller board based on the Microchip ATmega328P microcontroller and developed by. The UNO is the most used and documented board of the whole Arduino family. If this is your first experience tinkering with the platform, the UNO is the most robust board you can start playing with.
