In this video I am trying to generate QR codes and display them on tiny OLED display. This standard of 2D codes is incredibly popular and widely used. The best part? I found Arduino support specifically for generating QR codes.
Let me know how you like this video. Maybe you can use this it in your projects.

you became a teacher
your gains that will come back sooner or later
I really want you to win. I'm subscribed and stand by anyone who teaches science and technology.☺☺☺thanks
I am waiting for a video from Ads1115 to analog voltage converter mcp4725, it will definitely be watched.
QR codes with a cheap Oled display, cool !
I thought so too:)
Please give the link of qrcode library
github.com/ricmoo/QRCode
Excellent explanation. Please could you post the code link. Thank you.
I will try to provide the link tomorrow
I need the code too
The link is now provided. Sorry it took so long
@@marios_ideas Thank you!
Can you share the link to the code?
That link should be now in place
Is this 128*64 OLED display
Yes
When I am trying to verify the code, it is saying that QRCode is not declared in the scope. Please help me : (
What do you mean when you say "verify". Have you installed the library
@@marios_ideas Yeah, Before uploading I usually verify my code, i.e. - compile
@@suvamlivegaming7164 How did you resolve your error?
@@suvamlivegaming7164 the same thing happened to me, did you find a solution?
same problem! caould you solve it?¡
Dear Mario, how many textcharacters can be 'hidden' in the message that creates the QR-code?
I have not tested it from that perspective. But if add more characters at some point the code becomes bigger then 29x29. But this is for representing short texts like serial numbers, urls
