    look for "compatible microphones" and some of the examples mentioned are probably useful.

    There's a photo of the wiring and a video demo!

    This particular microphone has a DC offset. You probably want to include a high pass filter to remove the DC component. To see how, in Arduino, with Teensy selected in Tools > Boards, click File > Examples > Audio > HardwareTesting > Microphones > SPH0645.
