+## Arduino with network shield and sd-card
+This piece is a main controller. The main objectives are:
+ * Handle the communcation like receiving animation requests and process 
+ * Save and read animations from SD card
+ * Send data to the Rainbowduino
+TODO: More details to come
 
+## Rainbowduino:
+This piece receives data over I2C protocol and displays it on the cube.
+It has also some animations. In case there is no data to display it plays default animations.
+There is not much logic on this side. For more details please check the [Rainbowduino Wiki](http://www.seeedstudio.com/wiki/Rainbow_Cube)
