I bought a sound detector from SparkFun, intending to detect baby cries. However, I have zero ideas on how to begin with. I tried to read the Analog Input and see it values, I played a baby cries using youtube. But the values remain the same, it doesn’t change at all. Anyone can advise?
Thanks in advance.
Need to post a link to device , your code and wiring diagram
Is your Sparkfun audio detector one that has three different outputs?
If so you are probably not using the most appropriate output.
There is one output which is an audio signal, one which is the envelope of the sound, and one which is a digital output that goes high when a sound is detected.
It sounds to me as though you are trying to use the actual audio output, when you would be better off using the detected output.
