What we are going to do here today is how to make a cool LED cube at low cost

Step 1: INDRODUCTION

A LED cube allows us to create images and patterns by using the concept of an optical phenomenon known as persistence of vision (POV).The cube has 64 blue LEDs that make up its 4 layers (positives) and 16 columns (negatives).

Step 2: COMPONENTS REQUIRED

PCB (PCBWay)
Arduino Nano
LEDs Diffused, (5mm) - 64 Nos
Resistors (100 Ohms) - 4 Nos
Female Header pins
Cardboard

Step 3: PCB

Step 4: MAKING THE LED CUBE

1) Take a card piece and then make 9 square boxes with 2.5 Cm spacing

2) Drill 5mm Hole to the corner of all boxes

3) Insert 16 LEDs into the holes and bend the leads to the direction of the arrows using needle nose pliers

4)Solder all of the positive leads together and trim off the access of the leads

5)Now, you might have noticed that there are two gaps in the layer of the positive leads.

6)This can be solved by straightening a length of craft wire by pulling both ends of the wire with pliers and trimming two 1" sections that are then soldered in place.

7)After the hole positive layer is soldered together, flip the box over and start pushing the tips of the LEDs out of the holes in the jig.....

8)Follow this step to create 4 layers (Total)

9)Take the 4 LED layers and solder the negative leads together by stacking the individual layers on the top of each other.
