Can someone explain how the electret microphone breakout board works to identify tones? I don’t need the full techinical explanation, but how to make it work with an orangutan svp 324? I get that the AUD pin has to be connecter to one of the ADC I/O lines, but beyond that is confusing me
The breakout board does not identify tones, it simply amplifies the effect of output of the microphone transducer. The AUD output is simply that. To identify tones, you would have to determine the frequency of the sinusoidal waveform created by a tone.
