Getting Started with Arduino UNO

This doc explains how one can join your Uno board to the pc and add your first sketch. The Arduino Uno is programmed utilizing the Arduino Software program (IDE), our Built-in Growth Setting widespread to all our boards and working each on-line and offline. For extra data on how one can get began with the Arduino Software program go to the Getting Began web page.

Use your Arduino Uno on the Arduino Net IDE

Use your Arduino Uno on the Arduino Desktop IDE

If you wish to program your Arduino Uno whereas offline you have to set up the Arduino Desktop IDE The Uno is programmed utilizing the Arduino Software program (IDE), our Built-in Growth Setting widespread to all our boards. Earlier than you may transfer on, you should have put in the Arduino Software program (IDE) in your PC, as defined within the residence web page of our Getting Began.

Join your Uno board with an A B USB cable; generally this cable known as a USB printer cable


The USB reference to the PC is critical to program the board and never simply to energy it up. The Uno mechanically draw energy from both the USB or an exterior energy provide. Join the board to your laptop utilizing the USB cable. The inexperienced energy LED (labelled PWR) ought to go on.

Set up the board drivers

For those who used the Installer, Home windows – from XP as much as 10 – will set up drivers mechanically as quickly as you join your board.

For those who downloaded and expanded the Zip package deal or, for some motive, the board wasn’t correctly acknowledged, please observe the process under.

  • Click on on the Begin Menu, and open up the Management Panel.

  • Whereas within the Management Panel, navigate to System and Safety. Subsequent, click on on System. As soon as the System window is up, open the Gadget Supervisor.

  • Look below Ports (COM & LPT). It is best to see an open port named “Arduino UNO (COMxx)”. If there is no such thing as a COM & LPT part, look below “Different Gadgets” for “Unknown Gadget”.

  • Proper click on on the “Arduino UNO (COmxx)” port and select the “Replace Driver Software program” possibility.

  • Subsequent, select the “Browse my laptop for Driver software program” possibility.

  • Lastly, navigate to and choose the driving force file named “arduino.inf”, positioned within the “Drivers” folder of the Arduino Software program obtain (not the “FTDI USB Drivers” sub-directory). In case you are utilizing an previous model of the IDE (1.0.3 or older), select the Uno driver file named “Arduino bnok.vn”

  • Home windows will end up the driving force set up from there.

Open your first sketch

Open the LED blink instance sketch: File > Examples >01.Fundamentals > Blink.

UNO Load Blink

Choose your board sort and port

You will want to pick the entry within the Instruments > Board menu that corresponds to your Arduino board.

UNO BoardType

Choose the serial machine of the board from the Instruments | Serial Port menu. That is more likely to be COM3 or increased (COM1 and COM2 are often reserved for {hardware} serial ports). To seek out out, you may disconnect your board and re-open the menu; the entry that disappears must be the Arduino board. Reconnect the board and choose that serial port.

UNO Port

Add this system

Now, merely click on the “Add” button within the surroundings. Wait a number of seconds – it is best to see the RX and TX leds on the board flashing. If the add is profitable, the message “Finished importing.” will seem within the standing bar.

UNO Upload

Just a few seconds after the add finishes, it is best to see the pin 13 (L) LED on the board begin to blink (in orange). If it does, congratulations! You’ve got gotten Arduino up-and-running. When you have issues, please see the troubleshooting ideas.

Be taught extra on the Desktop IDE

See this tutorial for a generic information on the Arduino IDE with a number of extra infos on the Preferences, the Board Supervisor, and the Library Supervisor.


Now that you’ve arrange and programmed your Uno board, you could discover inspiration in our Mission Hub tutorial platform

or take a look to the tutorial pages that specify how one can use the varied options of your board.

  • examples for utilizing varied sensors and actuators

  • reference for the Arduino language
