LED matrix
LED matrix is a rectangular display module that consists of several LEDs. The following is an 8*8 monochrome
LED matrix with 64 LEDs (8 rows and 8 columns).
In order to facilitate the operation and save the ports, positive pole of LEDs in each row and negative pole of
LEDs in each column are respectively connected together inside LED matrix module, which is called Common
Anode. There is another form. Negative pole of LEDs in each row and positive pole of LEDs in each column
are respectively connected together, which is called Common Cathode.
The one we use in this project is a common anode LEDMatrix.
