Hey!
I’m working on a haunted house and I want a bunch of howls and growls and screams to come from different directions out in the woods. My plan is to use arduino with the mp3 shield and output through the 3.5mm jack. Then I would like to send the signal to several speakers that are placed out in the woods, but I want to control which speaker the signal is going to. I plan to line it up with some glowing eyes to give the impression of a huge beast that is changing locations.
How do I switch which speaker the audio signal is going to? My thought was to split out the lines in the 3.5mm jack and pass it through some relays to control the signal, but I want to know if there is an easier way? :think:
Thanks!
