Hi Everyone,
I am a maker and tinkerer and I am putting together a project where:
I am looking to use the electric signal in a wire pair that leads to a speaker
to turn on a switch / closing a circuit
for the duration of the signal coming through to the speaker.
that's the technical part- the real world version:
basically for halloween i want to hack a door chime which plays for ~15 seconds and use the signal that the chime's pcb sends to the speaker to instead turn "on" a small MP3 player which in turn plays music through it's own speaker instead. The mp3 player currently has a push button switch to activate its audio playback.
Let me know if you need any other info to help me out w this.
thanks
fabio
