Component Introduction:
Now, we are going to learn 8*8 dot matrix. It consists of 64 LEDs,
LED Matrix display:
located in every crossing of each row and column.
Welding pins on the 8*8 dot matrix:
When a row is at level 1, and a column at level 0 simultaneously, LED
lights up that is between high and low level.
For instance, if you want to light up the first LED, connect pin 7 to high
level, and pin A to low level; if you want to light up LEDs in first row,
connect pin 7 to high level, and pin A, B, C, D, E, F, G, H to low level; if
you want to light up LEDs in first column, connect pin A to high level,
and pin 0, 1, 2, 3, 4, 5, 6, 7 to low level shown as below figure.
