1/*
2 This example reads audio data from an InvenSense ICS-43432 I2S microphone
3 breakout board, and prints out the amplitude to the Serial Monitor. The
4 Serial Plotter built into the Arduino IDE (Tools -> Serial Plotter) can be
5 used to plot the audio amplitude data.

7 Circuit:
8 * Arduino Zero, MKR Zero or MKR1000 board
9 * ICS-43432:
10   * GND connected GND
11   * 3.3V connected 3.3V (Zero) or VCC (MKR1000, MKR Zero)
12   * WS connected to pin 0 (Zero) or pin 3 (MKR1000, MKR Zero)
13   * CLK connected to pin 1 (Zero) or pin 2 (MKR1000, MKR Zero)
14   * SD connected to pin 9 (Zero) or pin A6 (MKR1000, MKR Zero)
