The Electret microphone amplifier breakout board comes with a 20-20KHz electret microphone soldered on. For the amplification, the board uses the Maxim MAX4466, an op-amp chosen for power supply noise rejection.
This hello world utilizes the basic functions setup in the MAX4466 library to indicate volume levels read from the microphone using the 4 LEDs built in to the MBED
This library sets up and LED volume indication function and reading values from the Electret Microphone - MAX4466 Amplifier
