Professional attendance system using NodeMCU with a website and a Database.

- Hi, everyone.
Months ago, I made an Attendance system using Arduino UNO and RFID cards by saving the information about cards in Excel file
So in this video, I'm going to show you how to interfacing RFID-RC522 with NodeMCU and send the data to a web page and saving them onto a database.
you can use it to ensure all employees in a company or students had come in time every day and save their logs with their situations.
This the instruction that you need:
Notice:
In order to make the project working, the WiFi network should be a router network, not a Mobile hotspot.
In case you want to use the xampp server instead of WampServer you don't need to modify any config file, just copy the website files into the xampp/htdocs folder then continue the remaining steps.
Step 1:
1_ Add the ESP boards to the Arduino IDE.
2_Add the RFID library from Sketch--Include Library--Manages Libraries--search for (RFID)--then Install it.
3_After having the RFID-module wired to the nodeMCU like this:
SDA --- D8
SCK --- D5
MOSI --- D7
MISO --- D6
IRQ --- Not connected
GND --- GND
RST --- D3
3.3V --- 3.3V
connect it to the computer using a Micro USB.
4_Open the RFID_NodeMCU code and enter your WiFi setting(Name, Password) and your computer IP(you can know it from the command line by typing "ipconfig" then check ipv4), after that select the nodeMCU board from Tools--boards with the correct Port COM, and then upload it.
5_Open the serial monitor and set the baud rate to 115200 to check the connection status and the nodeMCU IP, save the IP(to put it in the server file "httpd.conf").
step 2:
1_Download the WampServer or xampp and install it.
2_Run it.
3_If you're using WAMPServer 2.1:
Click on wamp icon: Apache--httpd.conf--Add the nodeMCU IP to the permit list ( Allow from "nodeMCU IP")or try(Allow from all) next to this line: Allow from 127.0.0.1, then save it.
while If you're using WAMPServer 3.0.6:
Click on wamp icon: Apache--httpd-vhosts.conf--simply replace “Require local” with “Require all granted“ or "Require ip 192.168.xx.xx"(nodeMCU IP), then save it.
4_Click on wamp icon: Restart all services.
5_Click on wamp icon: www directory, then copy the website folder(login system folder) into it.
6_Click on wamp icon: localhost--login system--install.php(It should give you a success message, if not check the PHPMyAdmin password and username from (C:\wamp\apps\phpmyadmin3.3.9\config.inc.php) then put the password in (connectDB.php and install.php) pages.
7_Go to localhost/loginsystem/AddCard.php to add the users.
8_Then localhost/loginsystem/view.php to check the log.
It should appear on the serial monitor these messages:
for a new card or an available card:
200
successful
"the cardID"
and should the two LEDs blink
for a login:
200
login
"the cardID"
and should the red LED turn on
for a logout:
200
logout
"the cardID"
and should the blue LED turn on
**************************************
If you have any problems while using WAMPServer (like you get a "-1" or "-2" on the Serial monitor) please consider checking these steps:
1_The most important thing is the correct IP in the nodeMCU code(server IP) and in the permit list of the server apache config file (httpd.conf)or(httpd-vhosts.conf).
2_Make sure you restart all services (restart the server).
3_Check if your server has a password or not.
4_if you're receiving a message on the serial monitor that says "you don't have permissions to access this server" that means you must check the (httpd.conf)or(httpd-vhosts.conf) file because the nodeMCU IP is incorrect.
Or "404 Not Found The requested URL /loginsystem/postdemo.php was not found on this server" that means the website file doesn't exist into the www folder.
5_OR you're receiving just "-1" with the card ID that means there's no replying from the server, so check the server IP and enter it in the code.
**************************************
Download The diagram, the NodeMCU code and The website files from here:
github.com/InfinityWorldHI/No...
In case you want to use Arduino with SIM800L instead of NodeMCU then use this code:
github.com/InfinityWorldHI/RF...
Please, Let me know if there any issues with the code.
To add the ESP boards to Arduino IDE here the custom URL:

Hi everyone.
Recently, some guys have done the project and it has worked perfectly with a bit difficult and it still works very good for me on my Raspberry PI Cluster web server, but in another hand, some guys told me the project didn't work completely like logout doesn't work every time or they have a problem while sending the data to the server and didn't get the correct response from the server.
Therefore I've fixed all these problems in the new version and you can download it from here:
github.com/InfinityWorldHI/NodeMCU
In this version, the Card ID will appear on the Users Log page automatically each time you scan a card and you don't need to refresh the page any more.
On the AddCard page also you don't have to reload the page to add the new user just scan the card then the ID will be selected with a check green sign.
You can send your problem to my email("electbusinees@gmail.com")
or to my facebook page: facebook.com/ElectronicsTechHaIs/ if want that
or leave a comment and I will try to help you.
You're welcome.
Cheers...
Hey there mate! Any news yet? Thanks

hi sir. I am using Arduino Uno with ESP8266 that connects to WiFi. I don't have nodeMCU, so can I use ESP8266 instead of nodeMCU. I need Arduino Uno to communicate with my ESP8266 , that means code is uploaded to Arduino to control ESP8266. Thank you
Hi, yes you can, but first, you need to modify the code to make it work with Arduino UNO and ESP8266, each one needs a different coding. The RFID module will be connected to Arduino then the ESP8266 will send the data to the website. Arduino and the ESP will be interfaced by Serial in order to communicate.
We Respect and Love you don't stop helping peoples
This is a good start to program a electrical car charging wallbox to avoid unauthorized use. Only add a relay module and little program changes
I will try this project. This is a very good one.
Bro thanks a lot for this video. I took the contents of the code , modified it for our standards and obtained a research paper out of it.
You're welcome, thanks for telling me that.
I would like to read the research paper if you don't mind.
Could you send it to me, please?
SALAMAT PO NG MARAMI!!!!!!
Thank you for your time and support.............
It's fully working now
You're welcome any time.
thanks for your feedback, I appreciate that.
bro can you help me...The card id(before name) is not showing when addcard.php is accessed
I have learnt so much from you thank you and keep up the good work
Glad you like it and you find it useful.
Thank you for publishing this wonderful project. This is really a nice project for a newbie like me to learn new technologies. I request you to continue your service to this fascinating field. Please try to add MQTT server option too so that manipulating RFID data will be much more easier with GUI. Wish You all the Best.
I'm glad you liked it.
Good suggestion, thanks.
For me I prefer working with http requests and design my own IOT platform so there will be much things to handle with many problems to fix and that will make the learning process more interesting.
I'm working on many projects with MQTT and I like it as well.
Nice work.
You're Welcome.
Thanks.
Sir this is awsome project i loved it this is really awsome 😃
You're Welcome.
I'm glad it was helpful.
This is awesome. Could it be possible I could follow this guide for our project? And by the way, can I ask why can I not use a mobile hotspot just only from router? thank you ☺☺
Thx works pretty well
You're welcome.
Thanks bro it worked for me
I'm glad it was helpful. You're welcome
Can u make a exemple RFID credits system.. to chagre credit and use it and also show what balance left on card.
Hi , Thank a lot ... This is work very fine.
Hi, Good to hear that, My pleasure.
Thank you again and if possible I have a question
,too. In this project, when the card is first used it is recorded as an entry .The second time is recorded as the exit hour. In the following If the card is used for the third time, the exit time will change.
That is correct But if I want to be recorded this time as another entry,What should i do ? Thank you very much...
Oh, I see, yes you can make that. Leave your email and I will send you the modified page.

@@kishorerabha8920
I just followed his steps that he mentioned in the video description and everything went well as it should.
This project helped me a lot in my final year.
So you can make it works because the code is good not a bad one.
Hello. Would you mind adding the pin names on your diagram for the rc522? There are some card readers with different pin settings and it's hard to know which pin setting is in your setup.
of course, here's how to connect the reader to the NodeMCU:
SDA --- D8 (or any pin you want)
SCK --- D5
MOSI --- D7
MISO --- D6
IRQ --- Not connected
GND --- GND
RST --- D3 (or any pin you want)3.3V --- 3.3V

Hey, great video! What changes must I make if I want this system to work for an already existing database? What I mean is, I have an already existing database and I want the logs and users tables to be added to it and I want the system to work for this already existing database. What changes in code must I make to do this?
Hi,
Create the tables inside the existence Database than replace the database credentials in connectDB.php with yours.

Hello
excellent approach regarding the usage of the system.
I've made and an portable lcd with wemos so i can visualize any card or keyfob among all.
There must be something at the addcard php function which is not prossesing data the right way.
Lets say i have programmed 10 cards only by inserting them without username .
after i copy paste a card number and press select it shows up to the left.
Then i fill up user serial and gender and i press add.
Message appears that it was succesful But the user data went to another empty card number.
Please advice.
thanks in advance

thanks for your notice, I will upgrade the website and it will be available next Sunday.
I'm going to fix these bugs.
Thank you for the video, can you help me? I want to modify it by adding a relay, what program is used?
You're Welcome.
you can add the relay into this condition if you want it to turn on while login.

@@ElectronicsTechHaIs Thanks sir.
How if the rfid card number on addcard.php is refreshed automatically (only the no card part is not all pages).
sir how to do these project with esp32 module .could you please help me
Thank you so much for the amazing projects that you share.
but I have a question about the nodeMCU IP because it's changing every time I restart it. So how can I fix this problem?
I don't prefer changing the nodeMCU IP in the config file of the wampserver every time.
Thanks.
You're welcome.
open the code and put these line into it:
// config static IP
//IPAddress ip(192, 168, xx, xx); // where xx is the desired IP Address for the nodeMCU
//IPAddress gateway(192, 168, xx, xx); // set gateway to match your network
//IPAddress subnet(255, 255, 255, 0); // set subnet mask to match your network
in setup() section:
// Static IP Setup Info
//WiFi.config(ip, gateway, subnet);

Hi there, at first thank you for this wonderful video !
I was wondering is there any way to make this works on a web server, not on a local wamp or xamp.
Thanks
Hi, Glad you liked it,
Of course, you can use a public webserver, you just need to put the webserver domain name instead of the computer IP(Local Sever).
@@ElectronicsTechHaIs Thank you for your answer but i have a weird situation constantly getting -1 with the card ID I've checked many times the server IP address is correct (I've tried with numbers IP and the name of the web server same situation) ...any idea..Best regards
Are you using Local server or public server?
@@ElectronicsTechHaIs At first sorry for my late reply, I'm using public server
First, check if the domain name is correct.
Did you put the website files directly inside your public directory?
Second, Does your public server use HTTPS or HTTP?
Hello, have you tried doing RFID with Wifi Shield Cytron? Do you have any idea on how to combine both source code?
Sorry I haven't.
because of the nodeMCU a bit more easy to use. But you can give a try to make it by understanding how Wifi Shield Cytron works, Then modify the source code to make it suitable for Cytron Shield.
Hi, i just do it all correct, i have checked the ips but i still having the -1 on my serial monitor, what can i do? thanks
Hi,
Have you followed my instructions in the video description?
oh great teacher there is no problem if I do it with the module

isit possoble to connect just the arduino with xampp without nodemcu or ethernet shield , since im gonna connect the arduino to my laptop which runs xampp locally???
yes, you can.
There's a tool which provides communication between the Arduino and Local server via USB called "MySQLio".

I am facing a problem, data is not entering to user log, could you please give me a solution ? It's urgent for me
What the code should I have to typing.. I want to add one column for 'schedule' on side right after the Table 'name' column... Thank you
you should add a column into user and logs tables, also you need to add that column in view.php page and AddCard.php as well.
can i do it with the webpage without the nodemcu ? just using the arduino uno and rfid
Then you need a USB connection and a tool called MySQLIO
or you can connect a WiFi module called the ESP8266 V1 with the Arduino by connecting RFID to the Arduino then the ESP8266 will send the data to the website from the Arduino via Rx/Tx.
I will take about it in the next video.

Hello sir. Will it work if I change the rfid reader library to rdm6300 instead of rc522? because im using rdm6300 rfid reader for my project. your response is highly appreciated
Hi, It should work, if you made the right modification on the code.
whenever i will try to upload nodemcu code in board at that time i receive this error 'SPI' was not declared in this scope
Check if the SPI library is already exist or not.
I have a problem. There " hard bersetting via rts pin" . Can you help me about this problem?
Try to press the flash button on the board when you see "connecting....."
Does anyone know if there is a way to put all the information in an excel spreadsheet without having the rfid scanner connected into the computer..is there anyway to upload the data on to an SD card then transfer it from the card into an excel spreadsheet
That way I could have the scanner as it’s own separate unit
Here you don't have to connect the NodeMCU to computer just power it up by 5v then put it wherever you want, all the data will be sent to the website.
You can export the log to an excel spreadsheet from user log very simple.
Electronics Tech Thank you for the help. I’m still very new to this and trying to figure it all out.
