Need help for a minigame

Projects General Guidance

I want to create a mini game in which each player would have a box with:

  • an arduino
  • a 32 x 32 led matrix (or led panel)
  • two push buttons "yes" and "no"

There would be a game master (server) who could choose to display the image of his choice (which could be different for each box) on the players' boxes (for this part I was thinking of starting on a raspberry).

Here's my question: I'm having trouble seeing how I could send each box an image. I imagine a wired connection between the boxes and the "server". I have no idea how to transmit the image to a specific box

Thank you for your help and sorry for my english...

I send images from a ESP32CAM to a RPi using FTP. I setup the RPi to do the FTP server thing. For you the FTP file can be retrieved from the RPi.

Which file will the remote get? I suggest adding MQTT to the RPi so it becomes a MQTT Broker. Using either Node-Red or a program you write, the Broker can transmit the file name to the remote units. Upon receipt of the file name by the remote unit, the remote unit FTP's the file from the RPi.

Can be done using WiFi.

Thank you for your answer. I must admit that I don't see a better solution for the moment. I was also considering being able to send small videos, that would mean that the arduinos must have sufficient storage capacity.
