3D LED Cube
The 3D LED matrix used here is a 6x6x6 monochromatic LED Matrix. There are a total of 216 LEDs. The reason for choosing this size is that it provides the best of overall cube size and a number of good patterns great displays can be shown with the help of 3D LED Cube. Mono-chromatic LEDs from well known manufacturer are cheap and affordable; usage of mono-chromatic LEDs allows easier construction and programming of Cube. With monochromatic LEDs one has the choice of four mono-chromatic colors blue, red, green and yellow. A LED cube is like a LED screen, but it is special in that it has a third dimension, making it 3D. Think of it as many transparent low resolution displays. In normal displays it is normal to try to stack the pixels as close as possible in order to make it look better, but in a cube one must be able to see through it and more spacing between the pixels is needed. The spacing is a trade-off between how easy the layers behind it are seen and pixel fidelity. Since it is a lot more work making a LED cube than a LED display, they are usually low resolution. A LED display of 6x6 pixels are only 36 LEDs but a LED cube in 6x6x6 is 216 LEDs, an order of magnitude harder to make! This is the reason LED cubes are only made in low resolution. A LED cube does not have to be symmetrical; it is possible to make a 7x8x9, or even oddly shaped ones. CIRCUIT DIAGRAM The circuit shows the way 64 LEDs have been connected without having any need to expand the input /output pin count. Resistors are connected to each input line to avoid the LED s from getting destroyed by becoming a sink of high current.
