Hi every one i have recently started a new project the led cube.
But the problem is that i don't know how to program it and i don't want to do it. Is there any other way so that i can get some kind of pattern in my led cube.
thx in advance.

 

As in "i don't want to do it", does this mean you want someone else to do it for you?

 

LED cubes are usually driven using a technique known as "Charlieplexing", named for a Maxim employee. Do some Google searches on Charlieplexing, and see if you really want to try to build something like that out of logic IC's instead of a uC.

Your hardware requirements will get REALLY large in a big hurry unless you use a uC. They'll need a big truck to make the delivery.

no man i don't know how to program it and i don't even want to learn it
so i don't want to do it

 

So, you have a new project that you don't want to do. Is that right? Is it a school assignment? How much are you willing to pay to have someone do it for you?

i am willing to do the project but i don't want to program it i want a easier way to get some pattens

 

Just wire each LED to a SPST toggle switch. Mount all the toggle switches under the table so people won't know you are switching them.

Just buy a bunch of flashing LEDs and you'll get some sort of random patterns.

this was a bad idea.

ha ha ha i am not joking i need a circuit which runs on its own

 

here i found this diagram will it work?and can Charlieplexing or multiplexing be done in this?

 

Hello,

That circuit will not give a random pattern.
There will always be three leds in a row lit.
Also the leds are not correctly connected (there are no current limitting resistors).

If you want a random pattern you will need an other circuit and a lot of programming.

Fry's was selling them off the shelf. You could probably mail order it from them, since they have a online catalog.

I was serious. Unless you plan on using some form of programmable logic you'll have a difficult time setting patterns.
