 In this exercise, let's build a microphone preamp on the protoboard, acquire the audio signals on the AVR32 using the ADC, process the auditory signal to measure the RMS power (sound volume), and then use the average sound volume over the past few hundred ms of time to set the position of a servo motor.  In [[lab_4]] you will turn your prototype into a PCB schematic. In this exercise, let's build a microphone preamp on the protoboard, acquire the audio signals on the AVR32 using the ADC, process the auditory signal to measure the RMS power (sound volume), and then use the average sound volume over the past few hundred ms of time to set the position of a servo motor.  In [[lab_4]] you will turn your prototype into a PCB schematic.
