Introduction: 4*4*4 LED Cube
I made this LED cube to celebrate this Diwali in a Eco-friendly way.
The cube is made by using 64 Green LED's in all by stacking layers of LED mesh.
The challenge which remains in making this cube is constructing the cube structure itself .
Difficulty level - Medium
Step 1: Materials Required
You need the following materials for making LED cube :-
> Arduino Uno
>Green LED * 64
>Soldering iron and wire
Step 2: Test All LEDs
check for the continuity of each LED with a multi-meter.
Step 3: Diffusing the LED's
To Diffuse a LED rub the LED against a sandpaper.
Diffusing makes the LED appear dimmer, but gives a wider viewing angle of the light.
Step 4: Preparing a Jig
I am using thermocol to prepare the jig .
The jig would provide a frame to make layers of LED mesh .
Draw a square of 4''*4'' dimensions and punch out holes .
Step 5: Creating Layers
Bend the cathode of LED perpendicular to the anode leg.
Let the anode of each LED face vertically upwards.
Place the LED into the punched out holes in the jig.
Cut equal lengths of hookup wires and solder all cathode legs of the LED together.
Step 6: Stacking Layers
Thread hookup wire along the anode terminals which are facing vertically upwards.
Step 7: Test Each Grid
It is wise to test each grid with a multimeter set to continuity to rule out any defective LED or any broken contact in the grid.
Test the entire cube again after stacking all layers.
Step 8: Making Connections With Arduino
Step 9: Upload Sketch
Open you Arduino IDE and upload the sketch.
You can get the code from the link below
Step 10: Watch and Learn

Once again Happy Diwali to all.
