So i have made a prop bomb and i need to transmit to an audio track, i have thought of a few ideas but i want the simplest option.
I need something small the the arduino can just power from a pin, or to a relay allowing all 12v to the device which will transmit. then on the other end to play the audio track to a PA system.
Either i want it to transmit the sound itself or to just turn on the audio track on the other end, i need it cheap and simple... any ideas?
