Hi I am one of the older members and have just bought a Uno ,I made my cube and plugged it into the Uno ,ran some code written by others but all the Leds come on at the same time ,I deleted most of the code except for one line which I changed to be B0000,B0000,B0000,B0000,B0000,B0000,B0000,B0000,B0000,B0000,B0000,B0000,B0000,B0000,B0000,B0000,20, Which if I am correct should turn all leds off , but they are all on any suggestions would be welcome.
Hi, welcome to the forum and Arduino.
A lot of 4x4x4-cubes, using different types of hardware, probably exist, just like many ways to program them. Quite a lot of projects can be built/programmed in many different ways. Knowing little more as a line of data makes it hard to answer your question.
The more relevant info you give about your... cube (links/schematic/code), the easier it is for other people to help you.
