This is a step by step explanation of how to build a 5x5 LED cube using an arduino. I did this project for my undergraduate electronics class and it took me about 2 weeks to complete.

Note: Apparently, some of the links for the supplies and code aren't working, if you need them send me an email at amh02010@mymail.pomona.edu.

You can find a video of the working LED cube on youtube here:

And here's another:

Step 1: Supplies

I used www.mouser.com and www.amazon.com to order my materials for this project. The main parts needed are:
-125 LEDs
-30x 150 Ohm resistors
-5x 3-8 Line Decoders
-5 NPN Transistors

The manufacturer numbers and prices can be found in the attached document though the cost was about $40.

Additional required materials:
-Arduino uno
-Soldering iron
-Solder
-Sturdy wire (for structure of cube)
-Insulated wires
-Breadboard
-sockets (for decoders)

hi i want to learn arduino and its programing so can you help me to learn it i search every thing on google but eventually i came here and found this site so please help me to learn arduino my gmail id is <br>zainulislam23@gmail.com<br>my skype id<br>zainulislam49<br>my phone no is <br>03149053597<br>thanks in advance .......
I'm having troubles with this circuit. I have wired everything up exactly as you have said to do it but when I go to run the cube, all the outputs from all the decoders are high/ This gives me limited control but only over layers. All coloums are high but I can still control the transistors. I'm not sure where to go from here but I'm stuck. Any
never mind, I found out the problem to be that I just ordered any old 3 to 8 line decoders, but the ones I ordered work in reverse to these ones. They have 8 active high pins and using A0,A1,A2, you can set one of those pins to low. Make sure when buying parts, make sure you know exactly what it does. <br> <br>To note, DO NOT BUY 74ALS138N 3-8 LINE DECODERS
<p>So we used 74LS138N's, guess that's why we can't control individual pins. What one pin does, they all do and several columns will not light up at all. :/</p>
<p>Yeah you need to make sure the logic tables match up. Can you replace your decoders?</p>
<p>Could You please send me the final code? Thanks in advance. </p><p>nesjav_2468@hotmail.com </p>
<p>Hi! I have problems with programming, you could send an email with your code please. My email: lex0823@yandex.ru</p><p>&quot;Privet!&quot; from Russia :)</p>
<p>nice job. I am using this design for a college class project. Could you share your GREAT PCB DESIGN with us. (CAD files, did you use EagleCAD?)</p>
