Hello everyone, i'm new to this forum, so forgive me if something is not correct.
I'm using the following circuit for the amplification of a Piezo Sensor, i have replaced the mic in the circuit with the Piezo and am getting a decent output of approximately 5v, and i get nice Sound with a little noise when i connect the Output of the circuit to a Speaker/Earphones.
Checking the output on a 100Mhz DSO, m getting a proper waveform with a little noise.

All i want to do now is to get this audio signal into an Arduino UNO, and get the output of the Arduino into MATLAB, further for audio processing.
Can anyone tell me how can i achieve what i want?
