This presentation is about an LED cube. It describes the cube as having multiple LED layers that can be controlled individually by connecting each layer to ground while pulsing data to drive the LEDs. Instructions are provided on how to construct an LED cube in 4 steps, and it is recommended to watch a video for guidance on the construction process. Links are included to example LED cube videos for inspiration.

1. This presentation is about :-
led cube

2. At the first time I have seen it I was shocked
it was really amazing and I decided to take part in its develop even if by a little bit
Those are some links to get amazed 

3. Its construction :-
it is a multi layer led
Matrix Layer 1
Layer 2
Layer 3
Layer 4

4. Its construction (continue):-
Every layer has the
same
(anode in common-
anode type)
or
(cathode in common-
cathode type)

5. How it work :-
One of several ways to drive a led cube is to
control every layer alone , You send data to each
layer
while it is connected to ground in common cathode
and the other layers aren’t , and then switch to the
next one tell you drive them all.
do it again and again…..
