(4)Introduction of components:
The LED dot matrix consists of 25 LEDs arranged in a 5 by 5 square. In order
to locate these LEDs quickly, as the figure shown below, we can regarded
this matrix as a coordinate system and create two aces by marking those in
rows from 0 to 4 from top to bottom, and the ones in columns from 0 to 4
from the left to the right. Therefore, the LED sat in the second of the first
line is (1,0）and the LED positioned in the fifth of the fourth column is (3,4）
and others likewise.
