Great work. Runs fine with arduino uno, nano, but getting error in ESP32 ('QRCode' was not declared in the scope) on line 23. If I change the board to arduino uno it runs without any error. What changes I should make for ESP32?
ESP32 is the entire different microcontroller. My guess would be that the library is not ESP32 compatible. When I have some time I will chcek github documentation to see if it provides list of supported boards
absolutely support it. Good 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.
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
Hi, just wanted to clarify in case anyone has problems, SDA should connected to A4 and SCL to A5. Great tutorial!
Thanks!
No. It is Thanks to you:)
Your video is really good. Congratulations.
Super work and great explanation. Congratulations. Thanks.
This is awesome. Thanks!

Amazing and clear tutorial.. Thank you very much sir
Very nice!
Can you make an ardunio that emulates multiple bank cards? show me please
QR codes with a cheap Oled display, cool !
I thought so too:)
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
@@suvamlive4629 How did you resolve your error?
@@suvamlive4629 the same thing happened to me, did you find a solution?
same problem! caould you solve it?¡
Can you share the link to the code?
That link should be now in place
Great Idea
THX:)
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!
absolutely support it. Good

Is this 128*64 OLED display
Yes
Please it can't work with esp32
@@salahmohamed7657 are you asking? I have not tested it with esp
@@marios_ideasyes i am asking can you make a video for its way that is apart of my graduation project😊
@@salahmohamed7657 I will not write a code for your project for you.
@@marios_ideas thanks i solved the problem
Hi Sir!
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

Sir can you make these kinds of project ua-cam.com/video/netHzDIee1g/v-deo.htmlsi=xR9zjVMm2zQwdckq
