This example reads audio data from an I2S microphone
breakout board, and prints out the samples to the Serial console. The
Serial Plotter built into the Arduino IDE can be used to plot the audio
data (Tools -> Serial Plotter)
Circuit:
* Arduino/Genuino Zero, MKRZero or MKR1000 board
* GND connected GND
* 3.3V connected 3.3V (Zero) or VCC (MKR1000, MKRZero)
* WS connected to pin 0 (Zero) or pin 3 (MKR1000, MKRZero)
* CLK connected to pin 1 (Zero) or pin 2 (MKR1000, MKRZero)
* SD connected to pin 9 (Zero) or pin A6 (MKR1000, MKRZero)
