After getting the matrix working on the Arduino Uno R4 Wifi, naturally the next step was to get it working and connected to the Internet.
You’ll find the code here:
The secret is to include the WiFiS3.h, which the wifi library for the R4. Aside from that, the other thing that I did was move the settings (i.e. network, password, etc) into a io_config.h file to keep them out of the main code.
The end result is that the R4 now successfully connects to my Wifi and then to the internet. Upon success it wil display a check mark on the LED matrix on the device.
