This video is about the basic concept of digital display.,here we use MAX7219 module ( 8*8 Dot Matrix) ,There are several MAX7219 breakout boards available, two of which are more popular – one is the generic module and the other is the FC-16 module ,here we using generic module.
A typical single color 8×8 dot matrix unit has 16 pins, 8 for each row and 8 for each column. The reason for all rows and columns being wired together is to reduce the number of pins required. If this were not the case, an 8×8 dot matrix unit would require 65 pins, one for each LED and one for a common anode or cathode connector. By wiring rows and columns together, only 16 pins are required. This technique of controlling a large number of LEDs with fewer pins is called Multiplexing.
In this technique, each column is activated for a very short period of time and at the same time LEDs on that column are lit by addressing the corresponding row. The columns are switched so fast (hundreds or thousands of times a second) that the persistence of the human eye perceives the display to be fully lit. Therefore only a maximum of eight LEDs are lit at a time. Here we displaying some sprites and Transitions
Required stuffs:
1.Arduino Uno
2.Max7219( 8*8 Dot Matrix)
3.Jumper wires
