+ Esplora Led/Microphone
+
+ This simple sketch reads the microphone, light sensor, and slider.
+ Then it uses those readings to set the brightness of red, green and blue
+ channels of the RGB LED. The red channel will change with the loudness
+ "heared" by the microphone, the green channel changes as the
+ amount of light in the room and the blue channel will change
+ with the position of the slider.
