can i use a micro controller to switch audio or will i need to also use relays? Answered
hi, I'm thinking about making an audio linked house (each room can listen to music playing from another) (for details read my other post) basically all the rooms are going to be linked to a central switcher witch will have a micro prossesor in it, maybe an arduino or pic. my current design uses a whole load of relays connected to the digital pins via a transistor. i was wondering if there was an easier/simpler way to do this, maybe direct onto the micro prossesor?
