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.

#include <Esplora.h>
void setup() {
// initialize the serial communication:
Serial.begin(9600);
}
void loop() {
// read the sensor into a variable:
int loudness = Esplora.readMicrophone();
// map the sound level to a brightness level for the LED:
int brightness = map(loudness, 0, 1023, 0, 255);
// write the brightness to the green LED:
Esplora.writeGreen(brightness);
// print the microphone levels and the LED levels (to see what's going on):
Serial.print("sound level: ");
Serial.print(loudness);
Serial.print(" Green brightness: ");
Serial.println(brightness);
// add a delay to keep the LED from flickering:
delay(10);
