Upcoming Post: LED Cube

Hi! It has been too long since I last wrote a post on this blog. I'm currently working on multiple projects and really busy. This is one of the projects that I'm working on during some spare time.

It is called LED cube. There are quite a lot of them already made all over the place, with even bigger dimensions, but making it by ourselves gives a lot more satisfaction. As this one is just a 4x4x4 LED cube, the resolution and animation that can be made is quite limited, which is why I intended to make another one that is much larger, preferably an 8x8x8 cube (but still couldn't find the right time to do it.).

So, how do I do it? I followed this Instructable. It is really helpful and quite easy to follow, but I made some modifications. Instead of connecting each of the anode pins directly to the microcontroller, I used 2 74HC595N shift registers. It reduced the connections to the microcontroller, but makes programming a lot more complicated. But, being an ICT student, I took the challenge and wrote a program in Processing to help me write a program in Arduino. Talk about program-ception. :D

It is still not complete as I still have a lot in mind to improve it and the wiring should be much neater once I finished with it. I’ll share the schematics and some more information next time. Till then, goodbye and have a productive day.
