Addressable LED's - an example

(1/2) > >>

matsadona:
There seems to be a little hype about addressable LED's here lately (finally), so I just want to share an example of what can be done.
Not very arcade related this example, but it is a good showcase of the technology.

Felsir:
I'm a wrong to think that this is what ledblinky and ledwiz/pacled64 does? Or am I missing something important here?

Nope, that's exactly what LEDBlinky and Pacleds (and the other arcade related led controllers) are meant to do.

Shoot, have a look at the hall of fame thread to see individually controlled LED buttons that light based on their use in the current loaded mame game.

I like this project though. Maybe it uses an arduino or something to control the LEDs? Although that looks like a full mobo in the background.

The major difference with addressable LEDs is the amount of wiring. With non-addressable RGB LEDs, you would need 4 wires (3 if you daisy chained the + lead to each LED) running back to the controller. With addressable RGB LEDs, all the wires are daisy chained from one LED to another, leaving you with 3 or 4 wires (depending on LED type) coming from the controller, instead of a crap ton.

Ahhh... Each LED is paired with a micro controller and current limiter. Interesting.

Hadn't seen anything like that before, but it'd make wiring much nicer for certain!

Sparkfun has strips like that on which each LED is addressable, but those might be tough to wire.

Just found this though

much easier to separate for more distance between the leds
