Make your own 4x4x4 LED cube with an Arduino Uno
Pretty in pink
So, a few weeks ago I shared my LED cube on the site, but didn’t give a full walkthrough on how to build one.
Since then I’ve actually built a couple more, and I’ve pretty much got the process memorised now..
This LED cube uses an Arduino Uno micro-controller to create a stunning light show, and in this guide I’ll show you how you can make your own, as well as give you some advice on the things you should and shouldn’t do.
By the way, pink is optional. This cube is for my girlfriend!
Before you start
Before I get into part lists and then actually showing you how to make the thing, there’s a few things to say about the process.
First of all, you don’t need to understand or even care about the circuitry or the programming of this cube in order to build it. I’ll be describing the process in enough detail to take anyone with some basic soldering skill through to completion. That being said, I’ll also try and explain a bit of theory about the cube so that, if you want, you can understand about it.
Second, patience is key for this project. If you take your time and plan carefully then you’ll come out with something that looks the part. If you rush, cut corners or guess at things then it won’t look anywhere near as good. Practice also makes perfect. The cube that I show you in the pictures in this guide is actually my third cube using this design, so don’t be discouraged if yours doesn’t look as good. Of course, if yours turns out better, then I hate you.
Lastly, the most important thing in this project is that you have fun. I’m assuming that you’re interested in electronics, because you’re reading this article, so let’s get cracking on the next page with a part list.
