    Arduino to Arduino communications over Home WiFi หมดเขตแล้ว left

    Using 3 boards of Arduino Uno WiFi R4, and using my home WiFi network, I want to have one of the Arduinos act as the Master Controller and be able to exchange commands with the other two Arduinos (acting as clients). I am attaching a file that describes specifically the assumptions you can make, the initial configurations of the Arduino boards and the operational requirements for the Controller and each of the clients. The communication network needs to be my home WiFi and the template sketch should be very well document to understand all the parts or blocks of the code so I can tailor it to my own needs. The project should be fully tested and list or include all the libraries needed.
