Hi we are making a project that needs rfid card to display in the web. we are having trouble in our backend and front end but the main problem is hardware to database real-time. we are using Arduino ide and MySQL database. thank you for your help and guidance.
You can use an ESP32 and RFID reader for this purpose.
If you have trouble in your backend, there is a chance that that is the cause of the problem. Please provide details of the problem.
What problem? Be as specific as possible.
- Did you start with some simple examples? Do they work?
- If yes, what is your code for connecting and sending data? Don't forget to use code tags as described in https://forum.arduino.cc/t/how-to-get-the-best-out-of-this-forum/679966#posting-code-and-common-code-problems.
And there are probably a thousand other questions based on all possible missing information.
