I’m Varnit Goswami with username electrronix from Uttarakhand, India. Currently, I am studying at Jaypee Institute of Information Technology in ECE branch. Here is about my college project “4x4x4 LED Cube” and I made this project in the last summer vacation.
In this blog, I’ll show you how to make a 4x4x4 LED cube. The cube has 64 blue LEDs which make up it’s 4 layers(Anode) and 16 columns(Cathode). These are controlled by the Arduino Nano. Each LED can be addressed individually in software, enabling it to display amazing 3d animations!
1) Blue LEDs x 64
2) Arduino Nano
3) Breadboard wire
4) 100-ohm resistance x4
6) Power supply ( IC 7809, diode 1N4007 and 12v adaptor/battery)
7) Female headers
8) Breadboard wire
9) Soldering Iron and Wire
To make this project, watch the video https://www.youtube.com/watch?v=oNZr9_qr2ow
1) First, diffused all clear LEDs using sandpaper.
2) Form the loop at all negative terminals and bend all positive terminals of LEDs and trim the extra leads.
3) Drill the holes in the cardboard as given in the layout and insert the LEDs in the holes as shown in the picture.
4) Cut the copper wire according to the length of the frame (3.5 inches) and solder all positive terminals in a row, with the help of a copper wire.
5) Take a frame, and insert the copper wire in the loop at the negative terminal of LEDs. Solder the joints. Insert remaining frames, maintaining sufficient space between frames. Solder all joints.
6) Place the LED cube on the perf board and solder. Solder female headers, for inserting Arduino Nano.
7) Solder a wire to each frame and solder the free end to the perf board. Solder 100 Ohms resistor at each terminal of the wire.
8) The other end of the resistor must connect to Arduino Nano as following:
Layer 1 –> A0
Layer 2 –> A1
Layer 3 –> A2
Layer 4 –> A3
Connect the wires, from Arduino nano to frame as given in the circuit.
9) Now upload the code to the Arduino Nano.
That’s all guys, you made it!

This is a really good project for electronics geeks. I must say I had a great time making it and using it!!
