Question by O.G.: a home done wiring question; How do we have a tool which allows for tonal recognition?
In a office of egghead oddity we have been exploring how to have a series of gadgets. we wish my subsequent tool to do this: Recognize a single or mixed specific tones as well as bond opposite circuits depending on a tinge heard.
Does anybody know a great site to find easy guides? Or maybe a small suggestions of a usual intent which we can take as well as cgange to have it do what we want?
Thanks

look up audio filters.
you need a mike as well as an amplifier to modify a receptive to advice to a voltage. Then multiform audio bandpass filters to apart a opposite tones to opposite tools of a circuit. The outlay of a filters can any go to a diode detector as well as an opamp, as well as to a send to do whatever we wish to do with it.
You will need a audio vigilance generator of electric power as well as oscilloscope to get a filters operative correctly.
I’d do it a small bit during a time. Perhaps a single filter first, afterwards a mike as well as amplifier.
