• Update Modulino firmware in Arduino Cloud Editor

Update Modulino firmware in Arduino IDE

1. Connect the Modulino to your Arduino UNO R4 WiFi.

2. Connect the board to your computer and open Arduino IDE.

3. Go to the Library Manager and install the Modulino and ArduinoGraphics libraries.

4. In the top menu bar, open File > Examples > Modulino > Utilities > FirmwareUpdater.

5. Click Upload to upload the sketch to your Arduino UNO R4 WiFi.

6. The firmware update is complete when the sketch is successfully uploaded to the board and the text PAS is displayed on the LED matrix.

7. You can now test the Modulino by uploading an example from File > Examples > Modulino.

Update Modulino firmware in Arduino Cloud Editor

1. Connect the Modulino to your Arduino UNO R4 WiFi.

2. Connect the board to your computer.

3. Open the FirmwareUpdater example:

   • Click here to open it directly
   • Alternatively, open the Cloud Editor, go to Examples > From Libraries, search for “Modulino,” and open Modulino > Utilities > FirmwareUpdater.

4. Click Upload to upload the sketch to your Arduino UNO R4 WiFi.

5. The firmware update is complete when the sketch is successfully uploaded to the board and the text PAS is displayed on the LED matrix.

6. You can now test the Modulino by importing a Modulino Template.
