The LED matrix we decided to use is a 4 x 4 x 4 monochromatic LED Matrix. This is a total of 64 LEDs. The reason we chose this size, is that it provides the best of overall cube size, construction time & easier programming.

2. The LED matrix we decided to use is a 4 x 4 x 4 monochromatic LED
Matrix. This is a total of 64 LEDs. The reason we chose this size, is that
it provides the best of overall cube size, construction time & easier
programming.
TOOLS: copper wire, piece of cork ,computer with Arduino software
USB-cable , solder
PARTS: 64 led's ,16 resistors that go with the LED's 1
Arduino, some wire(isolated wire) 16 headerpins , 9V battery

3. LED Cube Construction: Step by Step Guide:

4. Step 1Drill the fixed holes(Making the rig):
• Draw on the box a grid with the lines 12,5 mm apart. Draw 4
lines horizontally and 4 lines vertically. You will now have 16
crossings. Drill some 5 mm holes (if your LEDs are 5 mm) at
the crossings of the lines. If you first drill small holes, the
location of your holes will probably be more exact.

5. Step 2 Bending the legs of the led:
Bend the 64 leds as shown in the figure

6. Step 3 Placeing the LED and solder them:
after that I fix the cathode terminal of the leds on the copper wire as
shown in the figure
Make sure that you don’t solder an anode to an cathode.

7. Then ,repeat this step for the 64 leds
So the result is 4 layers each has 16 leds as shown in the figure
Notice that there is along terminal in each layer

8. Step 4 Soldering the 4 layer LED
This step is a little difficult. By shortening the anode of the
leds to asuitable length ,then by soldering every anode to
the vertical copper wires (called column) as shown in the
figure ,in addition to the 4 wires of the ground

9. Step 5 fixing the led cube on the piece of cork:
in this step the most important thing is to be very careful
while you fix the 20 copper wires in the piece of cork an
advice you can fix a free copper wire in the places that the
wires of the cube will penetrate the piece of cork and then fix
the cube as shown in the figure.

10. so the view from the bottom after fixing the cube is as
shown in the figure

11. Step 6 is fixing the 16 resistors with every column :
fix one terminal of the resistor with the terminal of the column that penetrate
the pice of cork ,and fix the other terminal of the resistor with the isolated wire
,repeat this 16 times as shown in the figure .an advice not to use soldering in
this step as the column will be heated so the leds maybe falls and also the cork
will be damaged .

12. Step 7 is fixing the 16 header with every
isolated wire :
Fix each header with each isolated wire to be easy to connect with the arduino
as shown in the figure .

13. the code and the algorithms that used:
every line representing all the led cube ,every 4 parts
as(B1111,B1111,B1111,B1111) representing acomplete layer and every part
representing a row
so by this algorithm we can make any design we want
this is an example for adesign of some shapes
