+ *   - Within Loop() the serial-line is checked continously for a new dataset
+ *     for configuring individual RGB Led on the 20x10 matrix.
+ *     The dataset has the following format: 1122444666888
+ *     The meaning is: 11  (x-coord)
+ *                     22  (y-coord)
+ *                     444 (red)
+ *                     666 (green)
+ *                     888 (blue)
+ *     On successfully received of the dataset "OK\n" will be returned.
