How to make an LED Cube – 4x4x4 – Arduino Project

Introduction

It is fascinating to see that microcontrollers like Arduino can not only be used commercially or for industrial purposes but can also be utilized for various DIY and fun projects for beginners and enthusiasts. One of those DIY projects includes the LED cube circuit. It’s basically a three-dimensional cube, basically made from light-emitting diodes. So in this article, we are going to explore How to make an LED Cube – 4x4x4 using Arduino.

Hardware Required

You will need the following parts for creating this Project.

Working Explanation

In this LED Cube – 4x4x4 – Arduino Project, we have defined all 4 layers of the LED cube as A0, A1, A2 & A3. Also, we have illustrated all the 16 columns of the cube as 0–13 & A4, A5. When we uploading the code, the Arduino controller registers all defined layers and columns of the cube corresponding to the adjacent pins & sets the time integer to 250. After that, the Arduino defines two loops related to the output. Now, we have Set the function random seed() to take analog input from pin 10. In the void loop() the microcontroller randomly runs to display LED function.

Applications

• For decoration purpose.
• With other equipments like motion sensor, etc.
