Arduino talking to a RGB LED Matrix

[jri350]

You owe me two minutes and fifteen seconds!

0.26 lol

I'm assuming it was 4:14 when you recorded this?  lolol

[AlexisLS]

wow, it's cool ^_^ I'd like doing all those things, but i'm too bad u_u

[buggyiscool]

what Arduino board do you use?

[flakblas]

You just multiplex the matrix. So essentially each LED gets power for a fraction of a second and then the next LED is selected and powered and so on and so forth. So if you did it with the minimum amount of hardware and wires then each of the 64 LEDs would be getting power 1/64th of the time. Which is more than enough to maintain persistence.

Would be nice if you explained HOW you did this?

[nicotubetube]

hi, how you set all the 64 led, if arduino have only 14 pins out and the matrix have 16 2 of 8?

Where'd you get the matrix?

Was it expensive (most of the ones I've seen are fairly expensive)?

[graymalkin1234]

Look on ebay, they are on there for £2.20, not expensive at all

[dohzer13]

Thanks for the reply. Got any links?

I suck at searching eBay, but all the ones I can see are only dual colour. :(

let's see ... it's a clock ...

blue is hours, green is minutes and red is seconds ...

[monneyman3]

I don't get it...
