In this project, I created QR Code using : www.the-qrcode-generator.com/
The code file is saved in the .rar file format. I created a .rar file using Winrar V5.50, so to extract it, make sure you use the same version of Winrar that I use or the latest version or use the winrar extractor online.
SORRY IF MY ENGLISH IS CONFUSING, I USE AN ONLINE TRANSLATOR.

Nice! This is inspiring. I've gotten to the same point(web server/qrcode/pin IO) a couple months ago. I'm going to extend it to use mqtt and a PCI compliant docker container. Well done! I'm also going to try to trim it down to my own custom libraries. Stacking libs is messy at a certain point IMHO.
Thanks 🙂
Спасибо! Спасибо огромнейшее! Thank you! It work!
Good work mate...
Thanks for your sharing. this video is great and useful.
You're welcome.🙂
thank you so much!!!
You're welcome🙂.
Awesome
Thanks 🙂.
nice job
Thanks 🙂.
Hello in my project which is the smart stick for blind person I use an mp3 player to for example warn the person that the stick turns on or goes to sleep, I would need help to program the mp3 module so that in my code on the accelerometer if the cane lights up the mp3 module say the cane lights up using pre-recorded messages.
Hi your project is great. How does AP mode recognize qr codes, or is it necessary to familiarize ST mode with qr codes through the Internet?
Question does the function that is being called by the task is called once? or infinitely?
Hello Sir, could you tell me how to connect Leds to board? I am trying to use qr code to activate motors when it reads QR code.
Thank you
nice content !. I've a problem for the 01 barcode scan program, in my case there is a serial monitor show "can't create quirc object", can you provide a solution?
Thank u very much u helped alot!
👍🙂
@@utehstr Hey, I have a question. Can I connect my ESP32-CAM with the QR code reader code to a different ESP32 (Dev) module? I want my ESP32-CAM module to send the QR code result to the ESP32. I have tried a lot, but unfortunately, it does not work.
I tried to upload the code to the ESP32 and connected it via RX and TX.
heyy, i got a quirc.h library error while compiling. so what should i do ?
hello , how changing value to make scan every 20 second and waite another 20 second ?
Hi, I have a problem to upload sketch. It said error compiling for board ESP32 Wrover Module.
Here's the error message:
Arduino: 1.8.13 (Windows 10), Board: "ESP32 Wrover Module, Huge APP (3MB No OTA/1MB SPIFFS), QIO, 40MHz, 115200, None"
exit status 1
Error compiling for board ESP32 Wrover Module.
This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.
hi, great job! i have a problem, when i read a QR, it shw me this message: Decoding FAILED
Hi Uteh Str, thanks for this wonderful project and we need an help from this, is there a way we can send the data collected from the qr code to an excel file.
How to control the LED via ESP32 Cam, Which GPIO should the LED connected?
For me the video feed is a bit inverted, how to change that please help me with this thing
can this code also read barcodes (standard 128)?
When I am decoding the QR code of Mobile Phone display using esp32 camera module it is decoding the QR properly. But When I am decoding the QR code of Mobile Phone display using esp32 camera module it is NOT decoding the QR properly and It is also too much slow. Please Give me solution of it
Is cam esp32 enabled for OpenCV?
Hello, excelent vídeo 😊, i'm My code it Say that 'HTTPD_USE_STRLEN' was bot declared, it's the only error, what can i do? Thanks 😁
Hello i am making advance electronic voting process in which i have use Atmega32 microcontroller.
There are two features fingerprint based and aadhar card scanning.
Fingerprint part is done now i want to scan QR code of aadhar and configure with atmega32 for voting process for particular person
Please help me in coding section how should i do that?
please help me
the serial monitor show
Start configuring and initializing the camera...
Configure and initialize the camera successfully.
QRCodeReader is ready.
QRCodeReader running on core 0
but nothing happen after that, not show the "decoding failed or Success" like the video?.like the camera is still off. but i try on the example of camera web server, the camera on my esp is OK an still working properly
i have the same problem, did you solve it?
I tried this code but most of the time I get this message "Decoding FAILED
"
how can i use phone camera as scanner
i got error cam_hal: EV VSYNC OVF
Please help me. I have problem: exit status 1, compilation failed to ai thinker esp 32 module
May I know the complete error message.
THANK YOU for sharing this video with us i want to control a parking barrier with QRCODE if you know how i can do it let me know please
I am also doing that kind of project but i still can't even make ESP32 cam to read QR code even though I searched for QR code decoding Libraries.
hello~ I have problem when i used:02 ESP32 Cam QR Code Scanner Stream Web Server SM (Station Mode).
exit status 1
'HTTPD_RESP_USE_STRLEN' was not declared in this scope
X2 bro, did You solve it? I can't 😢
I already solve it, You need to chance that texto for a -1 because thats how is defined in the library, i don't know why it marked error but thats de solution.
@@samuelgrabois5754 please can you help me i want to control barrier parking with this code if u have any idea share it with me
Hello, thanks for the example.
i am having trouble with Guru Meditation Error: Core 0 panic'ed (LoadProhibited). Exception was unhandled.
I cannot seem to find the problem. Could you kindly help me out?
Hello, Where is the source of the power supply that you are using for the ESP32-CAM?
@@utehstr I am using a usb cable connected to my PC. I will try different cables. Additionally, I am using M5 Stack ESP32 Timer Camera X. Could there be other possible issues with that?
@@kaikim4652 I don't know for sure, because I've never used the "M5 Stack ESP32 Timer Camera X". I suggest that you use the same ESP32-CAM that I used for the video.
hello,idk what problem,cuz code upload nut it doest work ,what can i do?
Hey, what do you mean by code not working. Can you explain in more detail.
Hello sir, is it possible if not using web. Just serial connection only, so the result from scan is sending to serial monitor
have you found a solution?
Hello, excelent video, How can i get the rest of the libraries? (esp_camera,soc/soc and soc_rtc_ntcl_reg) Thanks C:
The rest of the libraries are already installed if you have Arduino Core for The ESP32 installed in the arduino IDE.
@@utehstr thanks i already solve the problem, saw it in a forum, the problem was the Arduino Actualization, the 2.0 versión dosent work so i instaled the 1.8.9 versión and the error disappear
@@samuelgrabois5754 👍🙂
Hi uthe str maze apse thodi help chai thi mera business idea ke lia to aapse baat karni thi
Sorry I don't understand your language, can you use English.
eaiiii irmão obrigadoo SALVOU MEU TCC SEU LINDO, GOSTOSO, ME MANDA SEU PIX QUE EU TE FAÇO UM AGRADO
Sir nice video!!! You gain another subscriber!! Can you share your code with us? We will use it as our reference for our project please 🥺🥺🥺 you have email or something cause I can't open it on WinRAR
Thanks 🙂
