LED cube project

Hey guys ,so was in progress of making the https://www.instructables.com/id/LED-Cube-4x4x4/step7/The-controller/ and i'm stuck on the controller step, a lot of people ware stuck on this as I see from the comments, and I can't find any help, would someone mind helping me? I have several questions, if you have time, I'd appreciate it if you answered them!  after zooming into the drawing, few questions remain: - resistors for the cathode and anodes, what resistance should they be? I'm powering this cube with 5.7v 1800ma nokia charger, current LEDs of mine run with a 120k ohm resistors, would these do fine?(connecting to the chip)  - On the left hand side, what are the 5V + > , GND connection mean to do? do they connect to the cube? or?  - also the connection 18-21 that have resistors and then are linking up to... cant read the writing, im guessing it should be the anodes as thats the forward current?  Hope someone could answer these for me? THANK YOU so much!  After i'm done making this project I will hopefully be able to make an easy to understand diagram for newbies like myself so they can work out this circuit themselves and wouldn't give up

How to wire a 4x4x4 led cube using Arduino Duemilanove?

I am currently building a 4x4x4 led cube and i want to use arduino to program it. This is the cube. How would I wire the arduino to the cube so i can control each led individually?

Asked by Electroinnovation 7 years ago


Hi I am thinking about making an 4x4x4 LED cube with 10mm LEDs for a 10 week project and wanted to ask about a few things which I am unsure of: Firstly:  I planned on following an instructables guide such as  https://www.instructables.com/id/LED-Cube-4x4x4/ or similar but these are all for the standard 5mm led . What I wanted to know is will these plans still work or will they need to be changed alot due to the more current being drawn? (apart from the obvious change in resistor values) Also I aren't sure whether to charlieplex the cube or multiplex it yet , Which is easier? In addition, Is the construction of the actual cube grid the same no matter which technique used ? {as i wanted to build the actual grid first to get it out the way then concentrate on the other parts} Any Help and tips appreciated  Thanks

I need someone to help me with me 3x3x3 and 4x4x4 led cube schematics?

Im making them to run off my arduino UNO, And Im sure most of you are tired of seeing these. But Im going to do a 3x3x3 and 4x4x4 before tackling the massive task of the 8x8x8. I want to make sure Im doing it right, And I drew up some very basic schematics as for what I need to do. Im hoping these are at least somewhere in the ballpark. 3x3x3 http://img846.imageshack.us/img846/8991/s340604p01wl.jpg 4x4x4 http://img64.imageshack.us/img64/8792/4x4x4blueprint.jpg So yeah, thats what I have so far, as for led's heres the specs: Life Rating : 100,000 Hours Emitted Colour : Blue Size (mm) : 5mm Lens Colour : Water clear Peak Wave Length (nm) : 460 ~ 470 Forward Voltage (V) :  3.0 ~ 3.4 Reverse Current (uA) : Luminous Intensity Typ Iv (mcd) : 6000(Typical) ~ 8000(Max) Viewing Angle : 20~25 Degree Max Power Dissipation(PM): 80mW Max Peak Forward Current(IFP): 75mA Lead Soldering Temperature : 240 Degree ( Operating Temperature Range : -25 ~ +85 Degree Preservative Temperature Range : -30 ~ +100 Degree Not sure what resistors I need though.

Coding to controll a 4x4x4 led cube with arduino duemilanove... Help please?

Okay, i know how to build the cube and to multiplex it to use only 12 pins. what i am going to do is connect each anode of each level and connect each cathode of each row, and each one will go to its own transistor. so i will have a total of 8 transistors for the anodes and 8 transistors for the cathodes, which i can further multiplex into two groups of 4x2 transistors. that makes a total of 12 pins on the arduino(i hope that makes sense ill add pics of what i mean to help) but what im asking is that i need help on writing the code for this project. i have a basic idea to run loops inside of loops to make more than one led look like theyre on at the same time(i believe its called persistance of vision)  but maybe someone more experienced would be able to help me out with this. thank you to anyone helps and A Happy New Year To All Of You!!!

How to multiplex a 3x3x3 led cube?

Im going to make an led cube, probably going to start off with a 3x3x3, probably going to be controlled by and arduino or a pic microcontroller.  I know i have asked a couple wuestions about this but hear me out, pretty much know how to construct the led cube now, but i am still kinda clueless on the multiplexing part. I saw this one video on youtube that showed how to do it for a 4x4x4, but i tried using his method on a 3x3x3 and ended up using more I/O pins than he did. SO can someone show me something on how to multiplex a 3x3x3 led cube?

Driving an LED Array without sourcing or sinking too much current and without too much resistance dimming the LED's?

I want to use a microcontroller (I haven't chosen which one yet) to control a large number of RGB LED's for use in an LED cube type display, and my concern is that assuming specs of about 20/25 mA source/sink capacity, how do i provide sufficient current to drive that many LED's in a multiplexed array? The Multiplexing also presents a problem, since a 4x4x4 RGB LED cube contains 256 different leads, each ideally with independent control, but I think i can work that out with multiplexing and the judicious use of MUX and de-MUX IC's.

What do I need to start getting into electronics?

I saw an instructable on here for an 8x8x8 LED cube, and was completely inspired. When I was younger (I'm 19) I built a few things out of those snap-together electronics kits, but nothing involving a soldering iron or a breadboard. I've bought myself a breadboard and a few little pieces to try to start out, but I know I need more--and I'm not totally sure what. On my list is a soldering iron (I have one but it's a piece of junk), red/black wire, a multimeter, and an assortment of resistors, and an arduino, but past that I still feel like I'm missing something vital. My current project list is: A 4x4x4 LED cube (just so I can know the fundamentals before jumping into an 8x8x8) A stereo (I have 2 car speakers that are just laying around, I'm hoping to turn them into something useful) Touching up my benchtop power supply (I built one out of a computer PSU but it looks.... not good) A high-power LED flashlight (my mom is into photography and saw a post about using an LED for an improv light source--the pictures turned out great, so I want to build one that has enough brightness to be used in a real photoshoot) An LED visualizer (This is one of the more daunting ideas I've had, I realize programming will be a bit difficult... I was hoping to use RGB LEDs and a microcontroller to handle the logic) I have a bit of experience in coding, nothing too impressive, but enough where I feel that I can grasp at least the programming of an Arduino (which so far looks user friendly and relatively simple [to me]), and on top of that I've been into computers and done a bit of tinkering with electronics before and so I know the basics of resistors (and LEDs together), capacitors, relays etc. Any advice would be greatly appreciated :)

Top LED Instructables

The number of awesome LED Instructables keeps increasing, and we want to show them off! We have an older list of top LED Instructables, but within the space of a year and a half, including the very successful Let it Glow! and Get the LED Out! Contests, we've gotten many more cool projects that light up with color due to LEDs. Here are, in no particular order, 10 more great LED Instructables for you to try (or just admire): LED Chess Set With some dedicated modifying, you can turn a cheap glass chess set into a beautiful, glowing version. It also inspired another Instructable, the Simpler LED Chess Set. &nbsp Synchronizing Fireflies A favorite of randofo's , this series of LEDs shows a possible way that fireflies synchronize lighting up at the same time. Turn Signal Biking Jacket Hand signals, meet technology: a biking jacket with controllable glowing turn signals built in. 4x4x4 LED Cube Make light-based designs and patterns come to life with a large cube of LEDs. Animated Multilayered Engravings Transform a simple engraving into an animated piece of art with LEDs. LED Pasties The LED pasties became an instant classic--a very simple, very creative upgrade of burlesque pasties. Daft Punk Replica Table The squares on top of this table light up individually and can be programmed to make patterns and designs. LED Creatures These LED creatures can be programmed to recognize each other and can be a great project for kids and beginner LEDers. Hard Hat LED Display Geeks and construction workers are not often associated, but this hard hat bridges the gap with its LED Pong display. Fiber Optic and LED Garden Make a glowing garden that looks good both day and night and never needs to be watered. Choosing these 10 was very difficult--there are an enormous number of great LED projects on Instructables.Enjoy these projects, and let there be light-emitting diodes!
