The 8 x 8 dot matrix is made up of 64 LEDs, each LED is placed at the cross point of a row and a column. When
the electrical level of a certain row is high and the electrical level of a certain column is low, then the
corresponding LED will light. If you want to light the LED on the first dot, you should set ROW 1 to high and
COL 1 to low.
