An electronic device used in decorative installations. LED cubes come in sizes 3x3x3, 4x4x4, 5x5x5, etc. By changing the speed of lighting and decay of LEDs in a cube, we create various visual effects: running lights, equalizer, 3d light installation.
Material :
- soldering board or solderless board
Tools :
- stripping tool
- ruler or caliper
- Soldering Station

As you can see from the figure, there is a third shift register, it can be used to send signals to the positive contacts. In this manual, this was not done and all positive contacts are brought directly to the arduino pins.
