QR code

Projects General Guidance

Hi everybody!

I'd like to know if it's possible to read and re-use a qr code with the UNO?

And with which library?

I'd like to know if it's possible to read a qr code with the UNO?

What part of the Arduino do you think is capable of scanning a QR code?

And with which library?

I use the Black Diamond library most of the time. Lots of books I haven't read yet, and more coming in all the time.

That's part of my question. I don't know actually, but QR library exist so it should be possible to get the information.

I thought it could be possible by the RX pin.

I don't know actually, but QR library exist so it should be possible to get the information.

That library must come with examples, and instructions, indicating what extra hardware you need.

To be exact in my question. I would like to know if its possible to get a QR code from a scanner.
As the convert-code is a string. Compare the result with an array whom activate outputs.

Am I understandable?

I'm sorry because I am a begginner in arduino and as a programmer,but I've seen this application:

and I would like to make a kind of this to my wedding...

RFID != QR code scanner.

What scanner are you thinking of? (link to product data sheet)
Which QR library are you referring to? (link to library repository)

I would like to scan a qr code. And get it through the RX and then execute the code. Do you think its possible by the UNO?

8

Yes.
Your (unspecified) QR scanner is the wildcard here, though.

Most bar code scanners were “keyboard wedges” - they sat in between your pc and your keyboard, and when you scanned something, it would essentially make your computer think you typed it.

Nowadays, I imagine most scanners behave like usb keyboards. That would be a problem for most Arduinos, because they do not support usb “host” mode.
