Introduction: Arduino – LED Cube 3x3x3

In this tutorial I’ll show how you can create your own LED Cube 3x3x3. I’m sure you already saw some similar projects to this one but you never took action and made your own. Now it’s time to make your own!

By the way you can find more project here: http://randomnerdtutorials.com/

Watch this Demo Video of my project:

Step 1: All Parts Required

  • 1x Arduino Board
  • 27x LED’s
  • 1x Stripboard
  • 3x 22k ohm Resistors
  • 9x 220 ohm Resistors
  • 3x NPN Transistors (for example: 2N2222, BC547, 2N3904)
  • Wires
(I included a picture with all the parts)

Step 2: Video Tutorial + Schematics

If you follow my video tutorial I think you'll understand how you can finish each step! If you have any problem please leave a comment below. (I also included my schematics in the pictures)

Step 3: Upload Source Code

Download the library here.

Be sure to download the library and unzip it to libraries. If everything is correct you should find an example in the Arduino IDE software under File > Examples > LedCube > ledcube.

Upload that ledcube example!

Step 4: Final Product

That's the final product!

Hi Guys!
The solution for the 'error' is use an older arduino compiler (for example: arduino-1.0.6) and the cube will work.

Uploading using IDE 1.0.6 worked for me! Thanks!

It was smart to use loops to configure the pin layout but I'm having trouble understanding the pin configuration and having trouble arranging different sequence of my choice. That's it.

simply following the stuff would show me what to do and not teach me how it works, right?

This is my second 3x3x3, only this time I put onto a UNO Proto Shield PCD.

Now to find a clear box to put it all into.

Thanks for the Tutorial Rui.

maybe you can check local variables. its seems to be variable problem.

HarshitA7 (author)mahfuz0972016-03-05

HI
Its very simple by the way.
You just have to get potential difference to blink any of the 27 led.
Put high on the longer terminal and low on the shorter one while coding. Its very easy if you no the basis of embedded C.

Hello, I'm very new to the entire Arduino & Maker movements so forgive me for my inexperience but I am confused about one portion of the schematic and would greatly appreciate some assistance.

In the instance of the two black jumper wires leading from the layer 2 & 3 transistors they appear to meet at the layer 1 transistor which I understand then leads its own wire to the Arduino board. However in the video tutorial the creator shows that on the PCB board all three of the jumper wires meet at the layer one transistors input, the question is, do I solder all three of these wires and the transistor input together?

Thank you.

hey question... do you use 3 different resistors?

author
SowrabhN (author)naomi.n.vandijk2015-09-25

U can use three different resistors the only difference it makes is the intensity of the LED glow...If u increase the resistance the intensity decreases...

author
Lance_Tronic made it! (author)2015-07-24

I made it....

Took about 10 hours over two days to construct. I modified the placement of the transistors and the construction went very smooth (with a lot of checking and double checking). The only problem I had was with the IDE not recognising my NHDuino UNO. Once I updated the CH340G USB drivers, it run like a dream.

Next is to build a UNO shield for this to plug straight into the top and then box it up.

Many thanks for the instructible, it is a great design, library and code.

it works but i had to use a diffent code yours since it was giving me an error this is a pic of it i am going to solder an at mega on my stripboard later this is just temporary to see if it would work

i didnt quite follow the tutorial so much as i used the diagram to get pin outs and kinda wired it my own way, i still think this is a great tutorial for anyone trying to get into led cubes... for mine i soldered the resistors and transistors right to the cube and then soldered jumper wires to the ends (i dont have perfboard handy) the code is easy to change and add new patterns with the webpage code builder. overall this was a fun relaxing midnight project to put together.

Hey.. I made your project and it's running but there is little bit problem with it. These LED are not producing so much light. some times if your room light is on you can't see the LED is glowing or not
