8x8x8 Led Cube Circuit Diagram

For each layer use two pn2222as in parallel.

8x8x8 led cube circuit diagram.

For a small led cube 3x3x3 or 4x4x4 you might get away with connecting the cathode layers directly to a micro controller io pin. Connections between power supply arduino and circuit. If you want a clearer circuit diagram you can download it from this link. Address selector step 18 transistor schematic use this schematic for the following step transistor schematic larger image step 19 transistor array the transistor array is responsible for switching on and off gnd for each layer in the led cube.

The power supply i bought this one. The whole structure will be based on a wood board. Pyroelectro schematic overview to clear up confusion that i ran into when building this 8x8x8 led cube i ve gone ahead and re drawn the schematic. I wish i would have went a little bigger.

The code is developed based on the work of chr from instructables. This phenomenon is a feature of the human eye and is responsible for the illusion that a. The dimensions of the cube will be 8 led by 8 led by 8 led for a total of 512 leds. My hope is that anyone who tries to re create this project can avoid the pitfalls i ran into.

Its a 120vac to 5vdc 10a. In this project we will exploit the persistence of vision. For an 8x8x8 led cube with only 10ma per led you need to switch 0 64 ampere. I should have ordered this multicolor music led cube version having three different colors rgb in one led as it looks more appealing.

Underlaying circuit of the led cube. The above image might not be very clear due to extreme compression. You can play music using any of these three. Parts list to build an arduino controlled 8x8x8 rgb led cube.

These will be used for a button and debug led later. The following image shows the complete circuit diagram of the 8x8x8 led cube using arduino nano. Some time ago i stumbled upon a youtube video showcasing an awesome led cube that displays animations in 3d. Led driver board circuit the first circuit is the schematic of the led driver board.

There are total 42 eye catching animations that start running as soon as led cube is powered some of which are outstanding. This circuit consists of the address selector 74hc138 the 8 data buffers 74hc574 with a 9 bit data bus control connector power circuit and power led. View full schematic schematic specifics led driver board changes. Below is the new schematic.

For a larger cube however the current going through this pin will be too high. A demo of the led cube in action.
