We have all seen different types and versions of LED cubes. Once they light up, we have always anticipated dazzling patterns. Some of us have even felt the urge to make one of those splendid LED cubes.
In this documentation, I will show you how to make an LED cube (4x4x4). I have used blue LEDs but you are allowed to use any other colour. This project took nearly two days for completion - one day to complete the structure and the next one to prepare the sketch. This project was specially designed for my Arduino Nano; unfortunately, the Arduino Nano had some issues while uploading the code. After several attempts, I realised that the problem was with the Arduino board and not my sketch. At first I used the Arduino Uno, but later I solved the issue with the Arduino Nano and used it.
- Arduino Nano - You can also use an Arduino Mega 2560 to manage I/O ports.
- LEDs (x64) - Generic
- Resistors (x4) - 220Ω
- Soldering iron - Generic
- Solder
- Cutting pliers
- Round-nose pliers
- Tweezers
- Ruler - 15cm
- Metal wires - 4" long and 20 gauge thick
- Wires
- Stripboard
- Cardboard sheet/ Wooden plank/ 3D printed template
Using your ruler, draw a grid onto a cardboard sheet/ wooden plank with 9 squares, each with a dimension of 1"x1". Carefully poke/drill a hole onto the points where the lines meet, and the diameter of the hole must be equal to the diameter of the LED.
Place the metal wires above the LEDs and solder the wires with the anodes of the LEDs. Then, place two other wires, one at the top and another at the bottom, and solder it with the four wires. Repeat this procedure for other three layers.
Carefully place 16 metal wires (4" long) in an arrangement like the grid you've drawn and solder each layer with the wires.
Your cube must look similar to the one in the images above.
