Hi there,

I'm an artist looking to collaborate with a tech genius on an art project. I want to build a device that uses voice recognition and displays the text on a scrolling LED display board, using the Arduino micro-controller board.

These guys have figured it out but are based in Singapore:

www.google.co.uk/amp/www.instructables.com/id/Voice-Input-Arduino-Bi-color-LED-Matrix-Scrolling-/%3Famp_page%3Dtrue

Is this something anyone has the know how to build? This would be a paid job.

Please also let me know where you are based

Best,
Dolly

There's a "gigs and collaborations" section here you know - a mod will likely move it there.

The scrolling LED matrix (a debatable way to go about the whole thing, frankly - I would use a matrix of WS2812's, or APA102's if the refresh rate of 2812's was too low, and that gives you full color so you can make it look a lot cooler (and you can crank it up blindingly bright so you can use it against a bright backdrop).

I'm currently booked up with paid projects for now, else I'd offer - but you don't really need someone like me for that. With the level of detail in that instructable, anyone with basic experience with Arduino and soldering should be able to follow their instructions, throw together the displays and upload the code (heck, they even link to the display modules they're using...) and get the same result they did.

Voice recognition is a hard problem. … Oh, I see - you just want to use an android app. So really this boils down to putting a bluetooth module on the arduino and parsing the data stream coming from the android. That's considerably easier.

Did you already have a scrolling LED display - a commercially built one? Constructing one from scratch is really more work than it needs to be. A commercially built one will already have firmware containing glyphs.

If you want to build a scrolling display, then that is a considerable amount of programming and electronics work. If you want to plug a microphone straight into your arduino and have the arduino interpret the sounds as words, I'd rate that as "impossibly difficult".

But if you are connecting this android voice-recogition app (and there is documentation for the data stream it produces) and having it drive a scrolling display that you already have (and there is documentation for how to drive it), than this is not super difficult.

What remains is describing what you actually want this setup to do. Would you like it to write the word "Yellow" in yellow when a person says "yellow" into the phone? That kind of thing.

Thank you both for your replies.


DrAzzy - I want it to look really simple with just one colour against black, like the messages that feed on trains and buses, so in that case is there any benefit of me using 'a matrix of WS2812's, or APA102's'?

PaulMurrayCbr - That also answers your question - I'm not imagining anything fancy like it showing up yellow when someone says yellow. Just that it will display what it hears people saying around it. I was imagining building it from scratch as Jollifactory have done:

http://www.instructables.com/id/Arduino-SPI-7-Bi-color-LED-Matrix-Scrolling-Text-D/

because I think the problem with buying one that's already made is re-progamming it, think it's easier to do this from scratch.

Sorry to you both that I don't really understand the technology.

I'll have to pass - this is a big project and not something that I would attempt to do remotely.
