+Example sketch for driving Adafruit WS2801 pixels!
+
+
+  Designed specifically to work with the Adafruit RGB Pixels!
+  12mm Bullet shape ----> https://www.adafruit.com/products/322
+  12mm Flat shape   ----> https://www.adafruit.com/products/738
+  36mm Square shape ----> https://www.adafruit.com/products/683
+
+  These pixels use SPI to transmit the color data, and have built in
+  high speed PWM drivers for 24 bit color per pixel
+  2 pins are required to interface
+
+  Adafruit invests time and resources providing this open source code, 
+  please support Adafruit and open-source hardware by purchasing 
+  products from Adafruit!
