28. 4x4x4 LED CUBE

The Arduino Uno is a programmable board that relies on a simplified C language. With skill, you can program the Arduino to do just about anything, including the project that this post featured, the Led Cube.

This uses 64 LEDs, which is a total amount of LEDs for the project (4x4x4). The way the led cube works is the way the Arduino switches the LEDs at certain points, creating a pattern through POV (persistence of vision), where the LEDs switch on and off at a fast frequency.

For starters, all 64 LEDs are fashioned into a cube, so you need a piece of cardboard, with holes in a 4x4 matrix, that way, you can push them in and make each layer perfectly.

The columns are made out of cathodes, and the layers are made out of anodes, all from the LEDs. Each layer is wired up to the resistors, which leads to the analog pins (A0 to A3). The cathodes of the LEDs are wired up in pins 13 to A4.
