Make your own SIMPLE 5x5x5 RGB LED Cube (Part 2)
video description
From what I can tell, all the LEDs share a common power supply and ground, but I don't understand how a single data wire connected to the data input on one LED can control color and brightness (from what I can tell, and also why the data input-output wires are connected in series. Do the LEDs have a special circuit component that allows them to operate in such a way?

Hello Scott, I created the cube all the way, but when I power it up, the signal does not travel thru some of the lights, I have tried everything, checked the wiring, changed the LED's and still stuck with the same problem, rather strange I should say, by the way, it is not my first cube, I have done a few before. Any suggestions?

Great movie.
I'm not so familiar with electronics, and in the link you provides, the 5V power supply cannot be changed to 5. 5 V as in the video.
I have a question please: 5V might make trouble, so you set to 5. 5.
Could you, instead, put a different resistor? maybe with lower resistance?
Thanks

Very good tutorial! Are there any design considerations of doing a larger Arduino-based cube using ONE data pin vs. one for each layer? Also, it's been almost 4 years since your video and I have found VERY FEW cube projects that uses addressable LEDs (PL9823, WS2811, APA-106, etc. Care to comment?

I'm having problems with the code. I'm not a specialist at all so is it possible to find a tutorial on it? I tried uploading examples from the same library you used, but it doens't even compile for me for some reason. Help?

A potential improvement for next time: add a wire and port to access the Arduino from the outside without opening it.
Also, the Arduino and power parts of the video are a little confusing.

Hello, we need to make a project with a LED cube and we would like to know if it's possible to increase the height, the height, the depth of the LED cube? Thanks for your answer. Good bye.

Hey! Great job! I was wondering if you could help! Seeing that I chose a 5x5x5 cube with arduino Uno as my project. could u help with the code and wiring?

sorry. but I'm not familiar with the data input and out. as far as I have ever known, there is a cathode and anode. can you elaborate? thanks.

What is that nifty low-profile wire stripper shown at 3: 47? I can see Deutsch on the label but can't make out the manufacturer.
