Arduino® UNO R3 9 / 26 Arduino® UNO R3 Modified: 15/11/2024 If you want to program your UNO R3 while offline you need to install the Arduino Desktop IDE [1] To connect the UNO R3 to your computer, you’ll need a USB-B cable. This also provides power to the board, as indicated by the LED. All Arduino boards, including this one, work out-of-the-box on the Arduino Cloud Editor [2], by just installing a simple plugin. The Arduino Cloud Editor is hosted online, therefore it will always be up-to-date with the latest features and support for all boards. Follow [3] to start coding on the browser and upload your sketches onto your board. Sample sketches for the UNO R3 can be found either in the “Examples” menu in the Arduino IDE or in the “Documentation” section of the Arduino website [4]. Now that you have gone through the basics of what you can do with the board you can explore the endless possibilities it provides by checking exciting projects on Arduino Project Hub [5], the Arduino Library Reference [6] and the online Arduino store [7] where you will be able to complement your board with sensors, actuators and more.
