Arduino IDE + NodeMCU V3 + MySQL + PHP | NodeMCU V3 with RFID RC522 uses MySQL Database and PHP

Arduino IDE + NodeMCU V3 + MySQL + PHP | NodeMCU V3 ESP8266 / ESP12E with RFID RC522 uses MySQL Database and PHP | CRUD. In this project video I use Arduino IDE 1.8.9 , Notepad++ V7.7.1 , XAMPP V3.2.2 , RFID RC522 and LoLin NodeMCU V3 ESP8266/ESP12E.

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.

Hi, if i want to make a servo motor rotate when i'm in the read tag (and is registed), how can i do that?

[kali]

I have question. I already achieve a 200 http status code but when I try another rfid card it shows -1 again and when I tap again the card that shows status 200, it will come back again to -1. Any idea what causes that? thank you

Hi, the UIDContainer exercise does work but when creating the registration page the tag id does not appear, I don't know what the error is due to. can you help me?

[ryanbarrera]

The 1st time I attempt to follow this tutorial, I was able to make it working.Then I put the hardware, nodemcu and rfid in a bag and tested it again for the 2nd time. It is no longer working. Is it possible that the rfid is damage.. I was able to upload the code to my nodeMCU. it' sjust that it cannot read the card.

@Uteh Str you did awesome work, I kept trying for 3 days, one simple error makes me dig all the codes and causes shit apparently found the error, Thank you so much, mate.

[jorsonlee]

Hi Uteh!
First of all I have to thank you show us such a complete and clear tutorial.
However, I had a problem :I only have Arduino UNO except NodeMCU. Is there a possible way to POST ID tag data via serial port ?
Thank you for helping me!

[Brinkster]

uh something is depricated an error occurred:
'bool HTTPClient::begin(String)' is deprecated

[jvvmmss]

Hello! Very good job! Thank you! Sorry, but I have a question.
We read ID and show only present ID on page "read tag ID". But how can we show ALL read tag on page "read tag ID"? Without updating?

[cj-gamingwallskiepog]

I have some of question .. for our thesis I hope you can help us ... Because our thesis is about locker security system using RFID . .
Will it work with the locker security system because I need this kind of system admin to control the locker

[johnpauldavid]

hi, thankyou for this helpful tutorial by the way,

I have a question I have rfid can i also put an mlx90614 temperature module in nodemcu ? i want to add it if is possible ?

Thankyou

[ananiasdanda]

Instead of NodeMCU V3 can i use an arduino uno and if yes is there something i should change?

[aylinmordel]

Im trying this for weeks for a project that im doing and the UID container doesnt show the id, i don't know what else to do, please help me 😥 life or death situation...
Im working with vscode, the id just show up in the serial monitor and that's it. Is a project for university... thanks

[LoquendoElHistoriador]

Hello friend, I used bootstrap 5, and there was no apparent problem, or is there any reason why you used version 2.3.2, will it cause any problems? Greetings.

[amiruleiman]

I have a problem where in "UIDContainer.php" the card ID able to displayed. But in "read tag.php" the form unable to display the user information. Same goes as the ID in registration form. Please help me to solve this problem :(
