Im absolutely new to hardware, and want to get started on some projects to pass the time and make life more fun!!
In my house at the moment ive got 2 dstv decoders, a radio and cd player in my “server cabinet” and I can connect any ONE of them to the speakers in the house (50-80w car 6inch speakers) ive got like 2 in every room.
So what I want to do is give every room a arduino,remote (IR) and make every room able to choose the input and volume…..
Ive read up on audio and I am completely confused, I have no clue what preamps ect does? For the inputs can I use 4 relays? Open current selected input and just close desired input relay? how can I reduce and increase volume?
