ABSTRACT
The project is a 3D LED CUBE DISPLAY (8x8x8 PIXELS) which displays different
patterns stored in the microcontroller. This 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 (actually it's voxels since it is in 3d) is needed. The
spacing is a trade-off between how easy the layers behind it are seen, and voxel 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 8x8 pixels are only 64 LEDs, but a LED cube in 8x8x8 is 512
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. Here we have an 8x8x8 shaped one. The code is written
in the C language using AVR studio and it is burned into the microcontroller using the pony
prog 2000.The circuit needs to be mounted on the mechanical structure or platform where
it displays the patterns that are stored in the microcontroller as indicated in the codes. The
patterns are displayed on a 3D structure which is made up of stainless steel rods. The
messages can be changed as per user need by rewriting the microcontroller’s in-built
memory. The complete display system circuit is power supply run on 5V, 2A which is
provided externally. This unique way of displaying messages is a very eye catching;
therefore its uses can in the field of advertising, toys, etc………

1. INTRODUCTION
A microcontroller is a computer. All computers whether talk about a personal desktop
computer or a large mainframe computer or microcontrollers have several things in
common like the CPU (central processing unit), execution of programs, presence of RAM
(random-access memory) etc… Microcontrollers are “special purpose computers”.
Microcontrollers are often low- power devices. A desktop computer is almost always
plugged into a wall socket and might consume 50 watts of electricity. A microcontroller has
a dedicated input device and often (but not always) has a small LED or LCD display for
output. A microcontroller is often small and low cost. Today the technology has advanced
to such an extent that has come a need to display electronic messages to satisfy all
purposes, whether it is business or domestic use. The solution found to satisfy this need is
the matrix display systems using LED‟s and LCD‟s. Different kinds of matrix systems are
available today which are capable of displaying messages, graphics, logos and moving
animation that are sure to capture and hold the attention of any audience. It provides
instantaneous, flexible communications when and where they‟re needed most. This LED
cube has 512 LEDs. Obviously, having a dedicated IO port for each LED would be very
impractical. We would need a micro controller with 512 IO ports, and run 512 wires
through the cube. Instead, LED cubes rely on an optical phenomenon called persistence of
vision (POV).If we flash a led really fast, the image will stay on our retina for a little while
after the led turns off. By flashing each layer of the cube one after another really fast, it
gives the illusion of a 3d image, when in fact we are looking at a series of 2d images
stacked onto one another. This is also called multiplexing. With this setup, we only need 64
(for the anodes) + 8 (for each layer) IO ports to control the LED cube. The main purpose of
our project is to build a 3D LED cube display using an ATMEGA32, high performance,
low power Atmel AVR 8-bit Microcontroller. It has advanced RISC architecture and 131
powerful instructions with most single clock cycle execution and 32 x 8 general purpose
working registers. Its function is to display the different patterns in 3D using 512 LED‟s.
By moving them fast enough, the output will be a human identifiable pattern or character.

also has a separate wire going to the controller board. Each of the layers is connected
to a transistor that enables the cube to turn on and off the flow of current through each
layer.

3.2 Explanation
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 trough it, and more spacing between the pixels (actually it's voxels
since it is in 3d) is needed. The spacing is a trade-off between how easy the layers behind it
are seen, and voxel 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 8x8 pixels are only 64 LEDs, but
a LED cube in 8x8x8 is 512 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.
This LED cube has 512 LEDs. Obviously, having a dedicated IO port for each LED
would be very impractical. Thus there comes the need of a micro controller with 512 IO
ports, and run 512 wires through the cube. Instead, LED cubes rely on an optical
phenomenon called persistence of vision (POV). When a led is flashed really fast, the
image will stay on the retina for a little while after the led turns off. By flashing each layer
of the cube one after another really fast, it gives the illusion of a 3d image, when in fact we
are looking at a series of 2d images stacked onto one another. This is also called
multiplexing. With this setup, there exists the need of only 64 (for the anodes) + 8 (for each
layer) IO ports to control the LED cube. There are anodes, cathodes, columns and layers,
for this led cube.
In order to light up an LED, we have to run current from the anode to the cathode.
The LED cube is made up of columns and layers. The cathode legs of every LED in a layer
are soldered together. All the anode legs in one column are soldered together. Each of the
64 columns is connected to the controller board with a separate wire. Each column can be

controlled individually. Each of the 8 layers also has a separate wire going to the controller
board. Each of the layers is connected to a transistor that enables the cube to turn on and off
the flow of current through each layer. By only turning on the transistor for one layer,
current from the anode columns can only flow through that layer. The transistors for the
other layers are off, and the image outputted on the 64 anode wires are only shown on the
selected layer. To display the next layer, simply turn off the transistor for the current layer,
change the image on the 64 anode wires to the image for the next layer. Then turn on the
transistor for the next layer. Rinse and repeat very fast.
The layers will be referred to as layers, cathode layers or ground layers.
The columns will be referred to as columns, anode columns or anodes.
The control unit is quite simple, 3 ports of the Mega32 were used:
one port controls 8 FETs for sinking the 8 ground layers
one port is wired to all 8 8bit d-latch inputs
the last port is used to enable the d-latch inputs
Since the d-latches are only able to sink or source 70mA on all 8 latches, we had to limit the
diode current to ~9mA, which is fairly enough for this type of LED.

4.4 PCB Fabrication
A printed circuit board, or PCB, is used to mechanically support and electrically connect
electronic components using conductive pathways, tracks or traces etched from copper
sheets laminated onto a non-conductive substrate. It is also referred to as printed wiring
board (PWB) or etched wiring board. A PCB populated with electronic components is a
printed circuit board assembly (PCBA).
PCB‟s are inexpensive, and can be highly reliable. They require much more layout
effort and higher initial cost than either wire-wrapped or pint-to-point constructed circuits,
but are much cheaper and faster for high- volume production. Much of the electronics
industry‟s PCB design, assembly and quality control needs are set by standards that are
published by the IPC organization.
4.4.1 materials
Conducting layers are typically made of thin copper foil. Insulating layers dielectric
are typically laminated together with epoxy resin prepreg. The board is typically coated
with a solder mask that is green in color. Other colors that are normally available are blue
and red. There are quite a few different dielectrics that can be chosen to provide different
insulating values depending on the requirements of the circuit. Some of these dielectrics are
polytetrafluroethylene (Teflon), FR-4, FR-1, CEM-1 or CEM-3. Well known prepreg
materials used in the PCB industry are FR-2 (Phenolic cotton paper), FR-3 (Cotton paper
and epoxy), FR-4 (Woven glass and epoxy), FR-5 (Woven glass and epoxy), FR-6 (Matte
glass and polyester), G-10 (Woven glass and epoxy), CEM-1 (Cotton paper and epoxy),
CEM-2 (Cotton paper and epoxy) CEM-3 (Woven glass and epoxy), CEM-4 (Woven glass
and epoxy), CEM-5 (Woven glass and polyester). Thermal expansion is an important
consideration especially with BGA and naked die technologies, and glass fiber offers the
best dimensional stability.

4.4.2 patterning (etching)
The vast majority of printed circuit boards are made by bonding a layer of copper over the
entire substrate, sometimes on both sides, (creating a “blank PCB”) then removing
unwanted copper after applying a temporary mask (e.g. by etching), leaving only the
desired copper traces. A few PCB‟s are made by adding traces to the substrate (or a
substrate with a very thin layer of copper) usually by a complex process of multiple
electroplating steps.
There are three common “subtractive methods (methods that remove copper) used for the
production of printed circuit boards.
1. Silk Screen printing uses etch-resistant inks to protect the copper foil. Subsequent
etching removes the unwanted copper. Alternatively, the ink may be conductive, printed on
a blank (non conductive) board. The latter technique is also used in the manufacture of
hybrid circuits.
2. Photoengraving uses a photomask and chemical etching to remove the copper foil from
the substrate. The photomask is usually prepared with a photo plotter from data produced
by a technician using CAM, or computer-aided manufacturing software.
3. PCB milling uses a two or three-axis mechanical milling system to mill away the copper
foil from the substrate. A PCB milling machine (referred to as a „PCB Prototype) operates
in a similar way to a plotter of the milling head in the x, y, and (if relevant z axis). Data to
drive the Prototypes is extracted from files generated in PCB design software and stored in
HPGL or Gerber file format.

5.2 Software Platforms Used
5.2.1 avr studio
AVR Studio is used by embedded programmers for programming and debugging for many
of the Atmel microprocessors such as the Atmega8 or even the Atmega128. While it has
support for assembly programming for those who prefer to use higher languages, it uses the
coff format for debugging. Beginning with version 4 AVR Studio has now moved to
dwarf2, and can be more readily used in conjunction with the open source gcc based
compiler WinAVR.

6. RESULTS
After successfully completing this project we came to know more about our project. It gave
us a lot of experience which will help in our future. The main advantages and limitations of
the project were identified. There are many applications for our project like in the field of
advertising, for making toys, to use as a study material, etc…. but the only limitation of this
project we had found is that it requires complete darkness, as it deals with the light. Since it
consists of the LED‟s it should be kept in a dark room for the perfect output.
