+// Example showing how to use FastLED color functions
+// even when you're NOT using a "pixel-addressible" smart LED strip.
+//
+// This example is designed to control an "analog" RGB LED strip
+// (or a single RGB LED) being driven by Arduino PWM output pins.
+// So this code never calls FastLED.addLEDs() or FastLED.show().
+//
+// This example illustrates one way you can use just the portions 
+// of FastLED that you need.  In this case, this code uses just the
+// fast HSV color conversion code.
+// 
+// In this example, the RGB values are output on three separate
+// 'analog' PWM pins, one for red, one for green, and one for blue.
+ 
+#define REDPIN   5
+#define GREENPIN 6
+#define BLUEPIN  3
+
+// showAnalogRGB: this is like FastLED.show(), but outputs on 
+// analog PWM output pins instead of sending data to an intelligent,
+// pixel-addressable LED strip.
+// 
+// This function takes the incoming RGB values and outputs the values
+// on three analog PWM output pins to the r, g, and b values respectively.
+void showAnalogRGB( const CRGB& rgb)
+{
+  analogWrite(REDPIN,   rgb.r );
+  analogWrite(GREENPIN, rgb.g );
+  analogWrite(BLUEPIN,  rgb.b );
+}
+
+
+
+// colorBars: flashes Red, then Green, then Blue, then Black.
+// Helpful for diagnosing if you've mis-wired which is which.
