Whether you are looking at building a sensor network connected to your office or home router, or if you want to create a Bluetooth® Low Energy device sending data to a cellphone, the Arduino UNO WiFi Rev.2 is your one-stop-solution for many of the basic IoT application scenarios.

Follow this simple guide to start coding on the browser and upload your sketches onto your board. If you want to program your Arduino Uno WiFi while offline you need to install the Arduino Desktop IDE. Full instructions on how to install it can be found in our Getting Started page.

The Arduino UNO R4 WiFi is designed around the 32-bit microcontroller RA4M1 from Renesas while also featuring a ESP32 module for Wi-Fi® and Bluetooth® connectivity. Its distinctive 12x8 LED matrix makes it possible to prototype visuals directly on the board, and with a Qwiic connector, you can create projects plug-and-play style.

With its built-in Wi-Fi® and Bluetooth® capabilities, the UNO R4 WiFi enables makers to venture into boundless creative possibilities. Furthermore, this versatile board boasts a convenient on-board 12x8 LED matrix and a Qwiic connector, offering ample space for innovation and unleashing creativity.

Whether you are looking at building a sensor network connected to your office or home router, orif you want to create a Bluetooth® Low Energy device sending data to a cellphone, the MKR WiFi 1010 is your one-stop-solution for many of the basic IoT application scenarios.

To use the Arduino UNO R4 WiFi board, you will need to install the UNO R4 WiFi board package, which is part of the Arduino UNO R4 Board Package. To install it, you will need the Arduino IDE, which you can download from the Arduino Software page .

If adding a WiFi shield, then Arduino’s WiFi library can be used instead. In this guide I’ve looked at: Cost of Arduino boards that have WiFi included; How to add WiFi to an Arduino (and how much that costs) How to use the Arduino WiFi; Example projects that take advantage of WiFi; How much an Arduino with WiFi Costs
