          We have designed LED matrix and seven segment displays in past few blogs. Here, we will see the basic concepts of LED cube. Schematic of a 2*2*2 LED cube is given below. As shown in the diagram, 2*2*2 LED cube has 8 LEDs. 4 LEDs at the top and 4 LEDs at the bottom. One of the important fact which had to be considered while arranging LEDs is the facility to turn on any LED individually. An arrangement of LEDs in cubical shape is given below.

          From the schematics, it is clear that, blue line indicates the cube. Cube has 8 corners. LEDs are arranged at the corners of cube. Red line indicates the positive terminals and black line indicates the negative terminals. Positive terminals at the top corners are shorted to get a common positive terminal (f). Similarly, positive terminals at the bottom corners are also shorted to get a second positive terminal (e). Negative terminals of 2 LEDs located at each edges are shorted to get 4 negative terminals (a, b, c and d). Using these 6 terminals, we can turn on any LED individually.

All the circuits, published in this blog is only after testing and getting proper results in my private lab. When you try these circuits, you should check the supply voltage, polarity of components, presence of childrens nearby and shorts in the circuits. This website will not be responsible for any harm happened to you or your components caused by your carelessness.
