+  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.
