Board Operation
IDE (integrated development environment)
Installing the Arduino Desktop IDE is required to program your Arduino UNO while it is not connected to the internet. You'll need a Micro-B USB cable to connect your computer to the Arduino UNO. The LED serves as a visual cue that also powers the board.
Arduino Web Editor
By just installing a little plugin, all Arduino boards, including this one, function on the Arduino Web Editor [2] right out of the box.
Since the Arduino Web Editor is hosted online, it will always be supported for all boards and include the most recent features. Start coding in the browser by pressing [3], then submit your designs to your board.
Arduino IoT Cloud
All Arduino IoT-enabled products are supported by the Arduino IoT Cloud, allowing you to automate your home or place of business as well as log, graph, and analyse sensor data.
Sample Sketches
Both the "Examples" option in the Arduino IDE and the "Documentation" portion of the Arduino Pro website has sample programs for the Arduino XXX.
Online Resources
After learning the fundamentals of what the board can do, check out the unlimited possibilities it offers by checking out intriguing projects on ProjectHub [5], the Arduino Library Reference [6], and the online store [7], where you can add sensors, actuators, and other components to complete your board.
