Thank you really much. For the project I would like, for example, to start a song first from speaker 1, after 2 seconds from speaker 2, after 3 seconds from 8 and so on. Do you know if I can find codes for this type of project ? Or can you give me an example that i can then modify with different variables of time and the relay to be activated/deactivate.
And the connection sequence between the various components would be pc (from which to start the song), arduino, relay module, speakers? Where would the amplifier be located?
I'm really sorry but i but I don't know anything about electronics
