LED Cube 4x4x4

Featured
Amazing 3 dimensional LED display.

64 LEDs makes up this 4 by 4 by 4 cube, controlled by an Atmel Atmega16 microcontroller.
Each LED can be addressed individually in software, enabling it to display amazing 3d animations!

8x8x8 LED cube now available, by popular demand:

Step 1: What you need

First of all, you need quite a bit of time to solder together 64 leds ;)

Knowledge list:
  • Basic electronics and soldering skills
  • Know how to program an AVR microcontroller - I will not cover that in this instructable.

Component list:
  • Protoboard. The type with copper circles.
  • Atmel AVR Atmega16 microcontroller
  • Programmer to program the Atmega16
  • 64 Leds
  • 2 status leds. I used red and green. (optional)
  • Max232 rs-232 chip, or equivalent.
  • 16 resistors for leds. (100-400ohms) will get back to this.
  • 2x resistor 470 ohm. for status leds
  • 1x resistor 10k
  • 4x resistor 2.2k
  • 4x NPN transistor BC338 (or other transistor capable of switching 250-ish mA)
  • 1x 10uF capacitor
  • 1x 1000uF capacitor
  • 6x 0.1uF ceramic capacitor
  • 2x 22pF ceramic capacitor
  • 1x crystal 14.7456 MHz
  • 2x tactile button
  • optional pwr switch
  • connector for 12v power
  • optional connector for 5v power

i see people can't seem to read.... it's not hard. 'save as' re-name

F6JRI6AFJ1I6CP0.tmp

to main.hex. upload to atmega16 chip and you are done!

i have a question  how do i use the zip file? the hex i can use it from windows to send it to avr but the zip i didn't know how to use..! can someone tell me if it s important o not?

the zip file contains the original naked coding files which you can edit if you want to, but if you dont know what you are doing... dont touch it.

if you uploaded the .hex file... you've completed the programming of the atmega chip and theres nothing more you need to do

How do you connect an avr to your pc for the code to load on it? And yes I do have linux

you need a gadget called a 'usbtiny' which is available on Ebay

so this is what i do. and i really don't understand what i do wrong.

Bartjeeh@linux-b5pm: cd /home/Bartjeeh/Desktop/4x4x4_ledcube
Bartjeeh@linux-b5pm:~/Desktop/4x4x4_ledcube> make
If 'make' is not a typo you can use command-not-found to lookup the package that contains it, like this:
    cnf make

in that folder are the following files

file:///home/Bartjeeh/Desktop/4x4x4_ledcube/F6JRI6AFJ1I6CP0.tmp
file:///home/Bartjeeh/Desktop/4x4x4_ledcube/Makefile
file:///home/Bartjeeh/Desktop/4x4x4_ledcube/draw.c
file:///home/Bartjeeh/Desktop/4x4x4_ledcube/effect.c
file:///home/Bartjeeh/Desktop/4x4x4_ledcube/frames.c
file:///home/Bartjeeh/Desktop/4x4x4_ledcube/main.c
if anyone could help me please!!!

change this file :

F6JRI6AFJ1I6CP0.tmp

to main.hex

then type

avrdude -c usbtiny -p m16 -U flash:w:main.hex

hello
I know, that last post was in 2008, but can you explain me why when i'm klicking "4x4x4_ledcube.hex" suddenly i am downloading something like : F6JRI6AFJ1I6CP0.tmp???? please so much help me...

before you click the link, right click on it and "save as", then change the filename to main.hex...

you need to rename int to 4x4x4_ledcube.hex

thanks

if you can log in to comment you can login and download the whole pdf!

i'm having some problems, when i use the make command, it responds with:"makefile: ***missing seperator", could someone plz help?, i want to use an ATmega8 or ATmega32, maybe somoene just could send me the HEX code, Karyochi@gmail.com.

dude, to change to the atmega32 you will need some sort of avr program writter like the one you can download from atmel (atmel studio).

open the makefile in atmel studio and then change this line...

mcu = atmega16

to

mcu = atmega32

and then compile and upload!

I recently made the cube. but i only have arduino to control it. Does anyone converted chr animation code to arduino? please helpp...
Steve25 egange3 months ago
I gues not, but why don't you buy an usbasp from ebay? It will cost you only 3 euro!
Sir can we use atmega 16 A instead of given above as I am only gettin A one on ebay so.... Please rply sir
egange Steve253 months ago
i already have asbasp programmer but i don't have Atmega32-16PU 40 pins. only atmega328 w/ 28 pins. im quite new in programming micro-controllers. i need to traslate chr code to be used in atmega328 or arduino. please helpp. :D

I want to make this for my first real project. I was wondering how important are the transistors and the capacitors. I have seen cubes that run with just LEDs and resistors so why the extra stuff?

The short answer is because he built his development board from scratch. If you look at an Arduino, all those components are placed on the board when it is manufactured (and then you have the input/output pins to use).

can any one post me the 4x4x4' 'compiled' hex.? i cannot compile it withStudio6.0, talk less of programming it with my TL866A.

I just published a 3D-printable template for this project. I hope it is helpful to anyone out there.

Hi guys
I built the circuit without the rs232-interface and programmed the (above attached) hex-file to the chip with a separate programmer. The status-leds are working, but none of the led's are lighting up. I measured the outputs (at cathode out from transistors and anode) and was surprised when my multimeter gave me a negative voltage.
Has anyone experienced the same problem ever?
I build it to without the rs232 interface and did not have that experience. Did you connect you're transistors right? My transistor had an TO-92 package (CEO). I nearly connected them wrong.
Hi Steve, You were right. I connected the transistors wrong. Now some Leds are lighting up but they only go on for about 10 secs and off again. Did you program the chip in circuit as in this instructable or on a separate programmer?
Yes i followed all steps in this guide. When i uploaded the program, 4 rows didn't light up. But after setting the fusebits it worked perfect.
If you also followed all the steps there might be an problem in you're wiring.

Hi Steve
It's running now! I indeed set the fuses wrong. thanks for your help! all the best
Great to hear! I'm happy that you got it working.

Can i use 16Mhz Crystal instead of 14.7456?
I just cant wait if ill buy the exact 16Mhz that i need. xD

Hey dude, nice work there, I'm trying really hard to make one myself, I have entered the atmel site but I see two different types of Atmel AVR Atmega16 microcontroller in PDIP.

Here is the link of the site too: http://www.atmel.com/devices/atmega16.aspx

Can you please tell me which one should I order ??? Thank you in advance
Steve25 manoulis5 months ago
I bought the atmega16-16PU. But you can use the atmega16-8PU aswell so the choice is yours

Thank all for answers. Now I have othe trouble, not all of leds is working and some always lithing very brightly.
Steve25 sadomukas5 months ago
Hi sadomukas. I can't tell what's causing this problem i only can give you suggestions. First check out you're connections again. If that's all good then check you're resistor value's. If the value's are good as well then check you're leds. There is a possibility that you're leds are damaged. To check this out, take out you're volt meter and put it on bleep ore diode. You're Leds should light up when you touch them. If they do not then they are broken and should be replaced.
If this is all good then the last thing i can think of is that you broke you're chip again.

Hope this will help you out good luck again!
