+  Circuit 1D-RGB Nightlight
+
+  Turns an RGB LED on or off based on the light level read by a photoresistor.
+  Change colors by turning the potentiometer.
+
+  This sketch was written by SparkFun Electronics, with lots of help from the Arduino community.
+  This code is completely free for any use.
