Using a piezoelectric buzzer in reverse as a microphone, the NerdKits team demonstrates how to design a single-transistor amplifier to amplify the signal. Once it's in the microcontroller, the information is used to make a sound meter display for MIT's Battle of the Bands 2009. (This is part 1 of a 2-part video!)
