Arduino® UNO R4 WiFi

14 Board Operation

14.1 Getting Started - IDE

If you want to program your UNO R4 WiFi while offline you need to install the Arduino® Desktop IDE [1]. To
connect the UNO R4 WiFi to your computer, you will need a Type-C® USB cable, which can also provide power to
the board, as indicated by the LED (DL1).

14.2 Getting Started - Arduino Web Editor

All Arduino boards, including this one, work out-of-the-box on the Arduino® Web Editor [2], by just installing a
simple plugin.
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 [3] to start coding on the browser and upload your sketches onto your board.

14.3 Getting Started - Arduino IoT Cloud

All Arduino IoT enabled products are supported on Arduino IoT Cloud which allows you to log, graph and analyze
sensor data, trigger events, and automate your home or business.

14.4 Online Resources

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 existing projects on Arduino Project Hub [4], the Arduino Library Reference [5],
and the online store [6]; where you will be able to complement your board with sensors, actuators and more.

14.5 Board Recovery

All Arduino boards have a built-in bootloader which allows flashing the board via USB. In case a sketch locks up the
processor and the board is not reachable anymore via USB, it is possible to enter bootloader mode by double-
tapping the reset button right after the power-up.
