Dual LED Matrix Message Board

I finally got the second LED matrix for my controller board. A few minutes of hacking at the code later, and it now scrolls the message over both matrices!
It looks really good in real life, and can do red or green LEDs (or both for orange), though the video only shows red.
Next step: get it to automatically receive the 'now playing' from the computer, currently I issue a command on the computer to send the currently playing track. Nearly done!

Yup, they're the medium RG ones.

[TheJugglingJohn]

awesome, i picked up the small rg ones and they work like a charm. just wondering, what chip are you controlling them with?

[randomskk]

Essentially this is an Arduino with six shift registers - the Arduino uses three pins to send a series of bits to the shift registers which then output them to the matrices, letting it control both screens using just three pins.

It's actually my own PCB with the same chip as the Arduino on top, but the idea is the same.

did you have to use red leds, i cannot see red very well :(

[randomskk]

The matrices do have green LEDs as well, but at the moment the program only illuminates the red ones.

we all just got LEDroll'd i guess

[Drwagnerish]

Awesome. I could spend the diagram and the program of the pic.

I appreciate it.

OMG that the geekiest rick roll ever!

[reesk92]

lol thats a good way to rick roll someone

[megabrontes123]

where did you get that pcb to run it on

[gurghet]

Did I just got Rickrolled?

[TheNameIsBradley]

Im a newbie at this sort of thing, how do you program the leds? can anyone reference me to a website that explains it?

[BartManNL]

TechnoRickRoll!

[andrewvpover]

I'd prefer those if they were easier to read off. E.g. LEDs that are dark when off (these ones appear white when off) and bright when on so that they can be easily distinguished and easier to read off.

I got LED-Roll'd!

This is quite possibly the coolest RickRoll ever.
