Install Arduino Uno Driver


There are some choices to be made when installing Arduino software and drivers in Windows 10. Arduino offer two ways of installing the Arduino IDE on a Windows PC — Windows installer file and a Windows zip file. Windows 10 will also install a default driver when an Arduino is plugged into the USB port of a PC.

Getting Started with Arduino and Genuino UNO

This document explains how to connect your Uno board to the computer and upload your first sketch.The Arduino Uno is programmed using the Arduino Software (IDE), our Integrated Development Environment common to all our boards and running both online and offline. For more information on how to get started with the Arduino Software visit the Getting Started page.

  • Use your Arduino/Genuino Uno on the Arduino Desktop IDE

Use your Arduino/Genuino Uno on the Arduino Web IDE

All Arduino and Genuino boards, including this one, work out-of-the-box on the Arduino Web Editor, no need to install anything.

The Arduino Web Editor is hosted online, therefore it will always be up-to-date with the latest features and support for all boards. Follow this simple guide to start coding on the browser and upload your sketches onto your board.

Use your Arduino/Genuino Uno on the Arduino Desktop IDE

If you want to program your Arduino/Genuino Uno while offline you need to install the Arduino Desktop IDEThe Uno is programmed using the Arduino Software (IDE), our Integrated Development Environment common to all our boards. Before you can move on, you must have installed the Arduino Software (IDE) on your PC, as explained in the home page of our Getting Started.

Connect your Uno board with an A B USB cable; sometimes this cable is called a USB printer cable

The USB connection with the PC is necessary to program the board and not just to power it up. The Uno automatically draw power from either the USB or an external power supply. Connect the board to your computer using the USB cable. The green power LED (labelled PWR) should go on.


Install the board drivers

If you used the Installer, Windows — from XP up to 10 — will install drivers automatically as soon as you connect your board.

If you downloaded and expanded the Zip package or, for some reason, the board wasn’t properly recognized, please follow the procedure below.

  • Click on the Start Menu, and open up the Control Panel.
  • While in the Control Panel, navigate to System and Security. Next, click on System. Once the System window is up, open the Device Manager.
  • Look under Ports (COM LPT). You should see an open port named ‘Arduino UNO ( COMxx )’. If there is no COM LPT section, look under ‘Other Devices’ for ‘Unknown Device’.
  • Right click on the ‘Arduino UNO ( COmxx )’ port and choose the ‘Update Driver Software’ option.
  • Next, choose the ‘Browse my computer for Driver software’ option.
  • Finally, navigate to and select the driver file named ‘arduino.inf’, located in the ‘Drivers’ folder of the Arduino Software download (not the ‘FTDI USB Drivers’ sub-directory). If you are using an old version of the IDE (1.0.3 or older), choose the Uno driver file named ‘Arduino UNO.inf’
  • Windows will finish up the driver installation from there.

Open your first sketch

Open the LED blink example sketch: File Examples 01.Basics Blink.

Select your board type and port

You’ll need to select the entry in the Tools Board menu that corresponds to your Arduino or Genuino board.

Select the serial device of the board from the Tools Serial Port menu. This is likely to be COM3 or higher ( COM1 and COM2 are usually reserved for hardware serial ports). To find out, you can disconnect your board and re-open the menu; the entry that disappears should be the Arduino or Genuino board. Reconnect the board and select that serial port.

Upload the program

Now, simply click the ‘Upload’ button in the environment. Wait a few seconds — you should see the RX and TX leds on the board flashing. If the upload is successful, the message ‘Done uploading.’ will appear in the status bar.

A few seconds after the upload finishes, you should see the pin 13 (L) LED on the board start to blink (in orange). If it does, congratulations! You’ve gotten Arduino or Genuino up-and-running. If you have problems, please see the troubleshooting suggestions.
