3x3x3 LED Cube Using Arduino

Hey guys, we are back with another new project. This time we will discuss the procedure to make an LED cube using Arduino. So without wasting time let us discuss the steps for making a 3x3x3 LED Cube using Arduino. Basically, it is a 3d arrangement of various LEDs with each other. In this 3x3x3 cube, we have three layers top, middle, and bottom. You have to make these three layers separately and then combine them to obtain a single cube. In each layer, there are 9 LEDs connected with each other. You can see in the diagram below that how to connect these LEDs together. For further information about this project please visit the original post of this project also bookmark TECHATRONIC.COM as all my further projects and tutorials will be pre-uploaded there.

How Does it Work?

In this cube, you have to specify the location of the particular LED which you want to turn on. When you combine the LEDs together and connect them to the Arduino then after uploading the code you will see some patterns that are made by the cube. You can also add your custom patterns but you have to change the code accordingly. The operating voltage of this cube is 5 volts, don't exceed it otherwise LEDs may get burn. You can see the images of the LED cube below.

Components Required

• Arduino UNO
• USB cable for uploading the code
• 27 LEDs
• three 1K-ohm resistors
• Breadboard
• Jumper wires
• Soldering Iron and wire
