Arduino Uno R4 Wifi Matrix display

The next controller I’m going to play with is the Arduino Uno R4 Wifi. I really like the ease and compatibility of the Arduinos I have used so far but the lack of WiFi I know will be a major limitation. So it make sense to explore a Wifi Uno.

One of the additional ‘nice’ features of the Arduino Uno R4 Wifi is that it has a LED matrix included on the board. Thus, the starting point is to try and get something to display on there.

First I tried displaying a simple emjoi. The code for this is here:

https://github.com/directorcia/Azure/blob/master/Iot/Arduino%20Uno%20R4%20Wifi/Emoji%20Display/main.cpp

and there are range of emojis to display.

I then uploaded the demo code here:

https://github.com/directorcia/Azure/blob/master/Iot/Arduino%20Uno%20R4%20Wifi/Text%20Display/main.cpp

to display Hello World on the matrix, which all worked as expected as shown on the image above.

The next step after getting something to display on the matrix will be to get the Wifi working.
