Hi,
I am trying to find (hoping it already exists) something that has multiple switches, each activated when a different sound is sensed... For example- a deeper tone, would set off switch a, where as a higher pitch sound, might set off switch b. I would ideally like up to 8 different switches connected to 8 different motors. I am by no means an electrical engineer, So you will have to explain it to me in lay terms. What is what I am looking for be called?
