+ Esplora Sound Sensor
+
+ This sketch shows you how to read the microphone sensor. The microphone
+will range from 0 (total silence) to 1023 (really loud).
+ When you're using the sensor's reading (for example, to set the brightness
+ of the LED), you map the sensor's reading to a range between the minimum
+ and the maximum.
+
+ Created on 22 Dec 2012
+ by Tom Igoe
+
+ This example is in the public domain.
