+// RGB Calibration code
+//
+// Use this sketch to determine what the RGB ordering for your chipset should be.  Steps for setting up to use:
+
+// * Uncomment the line in setup that corresponds to the LED chipset that you are using.  (Note that they
+//   all explicitly specify the RGB order as RGB)
+// * Define DATA_PIN to the pin that data is connected to.
+// * (Optional) if using software SPI for chipsets that are SPI based, define CLOCK_PIN to the clock pin
+// * Compile/upload/run the sketch
+
+// You should see six leds on.  If the RGB ordering is correct, you should see 1 red led, 2 green
+// leds, and 3 blue leds.  If you see different colors, the count of each color tells you what the
+// position for that color in the rgb orering should be.  So, for example, if you see 1 Blue, and 2
+// Red, and 3 Green leds then the rgb ordering should be BRG (Blue, Red, Green).
+
+// You can then test this ordering by setting the RGB ordering in the addLeds line below to the new ordering
+// and it should come out correctly, 1 red, 2 green, and 3 blue.

+// For led chips like WS2812, which have a data line, ground, and power, you just
+// need to define DATA_PIN.  For led chipsets that are SPI based (four wires - data, clock,
+// ground, and power), like the LPD8806 define both DATA_PIN and CLOCK_PIN
+// Clock pin only needed for SPI based chipsets when not using hardware SPI
+#define DATA_PIN 3
+#define CLOCK_PIN 13
