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

pliers

small screwdriver

solder

piece of cork

pencil

ruler

computer with Arduino software

USB-cable

PARTS: 64 led's

16 resistors that go with the LED's

1 Arduino

some wire(isolated wire)

16 headerpins

9V battery

LED Cube Construction: Step by Step Guide:

shows step by step instructions for building Images 3D LED Cube.

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. This plank with 16 holes will be the rig for your soldering.

Step 2 Bending the legs of the led:

Bend the 64 leds as shown in the figure

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.

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

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) so the result is we have 16 terminal of the 16 column as shown in the figure

Then we use another 4 copper wires to be soldering with every long terminal of each layer

that made in the previous step (step 3)(that used in the connection of the ground with

each layer)

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.

so the view from the

bottom after fixing the

cube is as shown in the

figure

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 .

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 .
