Received the microphone sensor from minkits, but couldn't get it work as what I expected. The analog reading value was too unstable to be used. Blowing air into the microphone didn't change the values. Did a lot of research, seems there are many people have the same problem with this microphone, but not many helpful solutions. One of the possible solution is fft library, but need spend more time to find out how to do it.
