Do the same with https://github.com/BornaBiro/IS31FL3731 (as stated in the manual linked above).
Install ArduinoJson v6 using the library manager.

The clients are MakerDisplays, you can get them here: https://www.crowdsupply.com/e-radionica/maker-led-display

They sponsored the boards, so I could try them (and thus write this article).
Modify the following variables according to your network and the host name of the computer running the server:
const char* SSID = "<YOUR SSID HERE>"; const char* PASSWORD = "<YOUR PASS HERE>"; const char* SERVER = "http://<YOUR SERVER IP HERE>:4444/balls";
Then, flash the software according to their manual: https://github.com/e-radionicacom/Maker_LED_Matrix_32.
First, start the server. Then, one by one add displays to expand the animation across all displays.
Turning displays off is not supported, i.e. they will not be removed. Turing a display off and on will result it being added at the bottom of the screen again.
