RFID-RC522 with Excel using Arduino (As a attendance system)
Вставка

- Hi, everyone.
In this video, I'm going to show you how to interfacing
RFID-RC522 with Arduino UNO and saving the information about cards in Excel file.
Login system or Attendance system.
For example to ensure all employees in the company come
in time every day and saved the Excel file where the names and each unique number stored when all employees had come.
The Excel file saves Login and Logout time.
Note: The card will detect only once and show you a message if the card already detected and saved.
-----------------------------------------------------------------------------------------------------------
Some guys told me that they have a problem while scanning the Cards
that problem was the Arduino detect many cards as the same with the same name even these cards had different IDs.
So I fixed the problem and Here's the new code,
Using this code you don't have to upload another code to scan the card's ID just upload this code then open the Serial monitor and scan your tags then replace yours with the other in the code.
I hope everything goes as you want.
Please read the comment in the code to better understanding.
Everything you need is here:

Note: I used this LCD driver: • Making LCD 16x2 driver...
with only 1 wire using SPI Protocol and Shift Register.
The reason why I used this method because RFID uses SPI protocol and
we could use his pins for another device using the same protocol and
save more pins to use them.

okay sir
using fingerprint please
Thank you very much sir!
hi, i used this code but still code not detecting the card and not showing the card number on serial monitor. please give me suggestion what can I do..
@@minalhingne1710 Yeah, me too. How to fix this. pls. help
I did this for my project and everyone loved it. Thank you so much ❤❤❤❤ you are such a smart man. Hats off
Glad to hear that
Can you send the project report please
@jacqui How did you get the data updated into the excel sheet please can you help
Bro ??
Thanks man, you really save me with this video, thank you so much.
It's my pleasure
I'm glad it was helpful
when i try to upload it go denied.. help, also does this work with 400 holes breadboard?
sir i have one problem please help me ot sir .........
i want to scan the card more than 2 time sir what can i do sir?
Serial monitor is not showing any outputs? The light on arduino uno and rfid module is working, what should I do
Make sure the serial monitor baudrate is set correctly to 9600
I have a question about the system. Students' names will initially write in the excel file. Then when a student reads his / her card, an 'X' will be placed next to the student's name. How can I do that. Please help me.
Yes you can do that, Google it
this is very helping for us students, thank you!
but why everytime i wanna use excel to open "cannot run the macro"PLX-DAQ-V2.11.XLSM". the macro may not be available in this work book, how to fix this?
Check if the Excel office is already installed on your PC.
sometimes "PLX-DAQ-V2.11.XLSM" isn't stable and might cause a problem while using it, because of that I made a new version with more feature.
@@ElectronicsTechHaIs it says that cannot run macro or disabled, how to fix this
I see, After opening the Excel sheet you have to allow running the macro (yellow warning message at the top).
can i ask how can you modify the nfc to a specific name?
Arduino : 1.5.6-r2 (Windows 7), Carte : "Arduino Uno"
'MFRC522'
rfid_read_personal_data:110: error: 'STATUS_OK' is not a member of 'MFRC522'

quoi faire dans ce cas please.'
HI can you please help i have my bachelor thesis topic i have picked rfid and i have tried what you instructed in the video however i cannot find rfid_serial_personal data i have only dump serial any advice how to find the solution please ?
hello sir, i want to ask if i need to connect it to a pc to get the real time data or can i just store the data in sd card and retrieve it later? thank you!

hey. I can not get my No. 2 card up in excel. what could the problem be?
Hello can I add gsm module for text message so it can be use for rfid attendance with database through excel with text message to parents
Hello, may i ask.. What if im doing a project that detects paper then send the notification to excel? Is it possible? Im using laser for the detection
Of course you can by replacing the parameters (Card ID, Name, Number) in the code with any parameters you want.
Bearing in mind you can't send a notification to Excel.
What are the LCD pins and LED
Hi, i was just wondering do i have to manually put a if statement for every id i add, as in i get i have to the uid but is there a way of writing the if statement for all uid i add (i have 200 to add ) thanks even if u could point me in the right direction that would help
Hello, since you have 200 cards then its better to have the system as a website on a server rather than using this version of the project, which that will make managing the cards easier and handy, so you can check my another video on how to make it with website and database, ua-cam.com/video/dXZiFx6RP6s/v-deo.html
let me know if you faced any issues.
Heya. Thanks for the amazing video your build was the best for us compared to the other setups we have seen. We are building a system for our practical and I have 2 questions. 1) Is it possible for the time in and out to display on the same line instead of separate entries? and 2) We are trying to integrate a system that will take the total time worked and work out the employees wage. What would the best way to achieve this be? Would it be adding extra code or stuff in the excel sheet?
Sir this is amazing project this is owsome 😀♥
You're Welcome.
I'm glad you liked.
@@ElectronicsTechHaIs thanku so much sir
Hello, i'm having trouble with the serial monitor, after uploading the code, the serial monitor only displayed string name 1,2,4,5 while 3 and 6 are not.
Hi, check if you modified the code correctly with your Card IDs.
Hello, I already checked them, but nothing's happening, 3 and 6 won't show up. Can i email you the code? So you can check it.
Oh, nevermind, i found out what's wrong, but thank you for noticing my comment.
what changes i should make ,if i want to set time in so that if the student comes in the class in time green led shoud blink otherwise red
pls help me sir....
you should use A real-time clock (RTC) module with the Arduino and modify the code to check the time in when the card scanned with your set time in. After checking the time in you should make an if condition to turn the LEDs as you want.
Very helpful and good informative.
I would like to know more about the code for multiple Card& Tag in a single Arduino RFID reader.
Thanks you
Glad to hear that,
You can check out the codes in my github repository, the link in the video description
Hello, I am having trouble adding more information. I have added the Card ID already, yet i do not understand how to add more informations on it. I tried adding an else if after the second card yet it doesn't work. What should I do? and if you have an email, might you check whats wrong with the code I added? Thanks in advance.
Hi, send to this email your problems with the code, and I will help you with it.

hello, i can scan the rfid tag already, and changed the name of the card also, but then when i upload the code at arduino, i receive message error on how port com3 couldt complete sketch. please help me
Hi, what is the error message?
Please help me Sir, there is a problem while putting port=3 and baud=9600 in PLX-DAQ for excel. A popup comes and says-
"COM Error: Error (5): CommOpen (CreateFile) - Access is denied.
Aborting!
"
this is the complete problem. Please help me
Overall code is running fine on serial moniter, Thank you for this.
Hi, the Serial monitor must be closed while opening the PLX-DAQ tool.
hi sir ,i have some problem.when i tap the card i can not get any data in the excel or serial .can you plz tell what is my problem?
the serial must be closed in order to send data to excel sheet correctly.
I kinda need an asnwer asap CAN I USE NFC CARDS INSTEAD OF RFID??? Just label the Nfc chips as someones id and then use it in the program
Yes, of course you can use NFC, you just need a NFC reader
how can i add sd card module for the program to save the information if anything happened in the excel
You need to add SD module and save the data inside it as JSON or as txt file.
Good day Sir
Can a use it for :Time in/out ? (Calculate the time between 2 uses of 1 RFID card)
Hi Electronics Tech! We know that our world is in a world pandemic as of now. Is it possible to have this RFID Attendance System but it also includes the person's temperature? Thank you for your kind response.
that's a very good question.
Can you help me with the coding?
I really need help because I've chosen this as my thesis paper and I need to make a prototype
@@mrvnmedina0908 what happened to your thesis are you able to make it with a temperature sensor?
we have similar thesis :)
Hello .. I have an Arduino uno and i connected every thing probably but it didn’t work !! may be the arduino is the problem, may be because it’s not a genuine one ... or what could be the problem ? @Electronics Tech
Hello, Please, recheck on the wiring and try to upload an example from the library examples.
Com error 5 shows up when i open the excel sheet
How can i fix that?
Is it possible to close the Excel window while the acquistion goes ahead?
Yes its possible, Check the included PDF.
HI GOOD EVENING. what kind of card did you use?
Good day! Can we convert the RFID to QR code generated attendance system?
does it need to be connect to the system while scanning the RFID tag?
Yes
How about from laundry machine to micrsoft excel sir?

My pleasure,
sir i want to use two RFID with one Arduino uno
actually i was connect between first and second RFID to Arduino in Same pin but in this case two RFID didn't work
but if i connected all pin in same without connect SS_pin "pin 10 in Arduino" , and connect first RFID SS_pin to Arduino pin 10
in this case the only first RFID will work and that is same with second if i connected SS_pin to Arduino pin 10
but if i connected SS_pin from first and second RFID to pin 10 in Arduino in same time the first and second RFID didn't work
how i can change in your code to add another SS_pin from second RFID to Arduino to work the first and second RFID in same time
First, you have to define each SDA pin something like this
MFRC522 A(A_PIN, RST_PIN);
MFRC522 B(B_PIN, RST_PIN);
A.PCD_Init();
B.PCD_Init();
Google it you will find something useful.
Great tutorial !. I have Few questions: What if I want to extend it functions to open a door (using a relay for example). I am using NodeMCU. I would like it to read from a preexisting excel ( that will be stored on an sd card or online ( on a server) and then authenticate the cards ( if the scanned card is registered on the server, it will turn on the relay and record the exact time and record success, if not it will still record the card with failed, but not turn on the relay. So the node MCU will have an sd card module with two files ( the predefined with all authorized card numbers, and the blank one to record the data). Sorry for that long text, but your help will be very apreaciated
You're welcome.
first, check out this video: ua-cam.com/video/dXZiFx6RP6s/v-deo.html
to give you some knowledge on how RFID module works with NodeMCU.
You can modify the website code as you want in order to make the nodeMCU execute your command like turn on a relay.
By this way, you can save every change that happens on your system and check it from anywhere plus it's easy to use.
In the next video, I will make a project using SD card to store the data.
stay close.
I have made this project. It is working properly. Every card is getting detected.on first time detection it is showing data in excel sheet and on second time detection it is not adding data in excel sheet. But i want to modify project like on second time detection,data should not display on excel if we are scanning card for second time within 1 minute after scanning for first time. After 1 minute if i scan same card then it should display data. Is it possible!? Please help me ASAP sir.

Hi. I just want to know how to record the time in and time out for this one in the excel?
the time in and time out are recorded when the Arduino sends the Data to the Excel using this line Serial.println("DATA, TIME");
Sir I did the connections and well bulit is showing only Read personal data on a MIFARE PICC: till it was showing correctly but that Rfid card is not scanning by the scanner
Sir please reply we have to submit project by tomorrow
Did you solved this?
if i want use a 20x4 display what is the programation?
Nothing changes only lcd.begin(20,4) in the setup() section.
lcd.begin(total columns, total rows) This function is used inside the setup() to initialize the size of the LCD you're using.
hi, just want to ask if how many rfid card can 1 arduino handle?
The Arduino can handle How many cards you want, I think.
I advise you to make a program in any language you know to manage the whole process (Save data, Validation, Adding,.....)
I mean the Arduino just detect the Cards then the program takes the rest.
Should I need to buy the office by microsoft to use the exel sheet .sir please
No you don't have to.
hello sir..could you plz send final code of the project with LCD + diagram connection Arduino Uno+RFID + LCD because the links in the description for lcd part are not working thanks in advance
hi, i just want to ask. i've tried using 2 rfid one inside and outside of the door for time in and out. but the plaxdaqv2 can't have more than 1 com port in 1pc/laptop.
you can't connect two Arduino with PLX-DAQ.
So to solve that use Arduino mega with two RFID modules and set one for Time In and the other one for Timeout then read the tags to send the data to Excel tool
but you can use just one RFID module and nodeMCU with a web interface and save all needed data in a Database and make it professional
thank you so much for your answer. i'll give you a feed back after i finished connecting the two rfid's in one arduino UNO by just jumping wires using bread board??.
@Electronics Tech I've done it. now for the last question. can i add as many cards as i want?
Of course, you can.
resistors and capacitors are not needed anymore right?

how i want to make sum total item ? i do smart shopping trolley. but i dont know how to write the code for addition. can u help me ? at least show me an example and what instruction that i can put the code for addition. thankyou
First, you must define a variable that saves the total price like(float total_price = 0;), this variable will update when you add a new item(float item_price;)
in code:( total_price = total_price + item_price ;)
Hi 😂
I followed all the instruction but when it's time to read the NFC tags it doesn't appear it just only "Name,Number, Date, Time"
Then use this code bit.ly/RFID_Excel-6Tags and modified it as you want
it will send to Excel these parameters "ID,Date,Name,Number,Time IN,Time OUT"

It's very simple just initialize the library with the numbers of the interface pins as you want. like:
LiquidCrystal LCD (1, 2, 3, 4, 5, 6);
LCD RS pin to digital pin 1
LCD En pin to digital pin 2

because you have to change the RedLed and GreenLed pins to different pins like A0, A1 then reconnect the LCD and it's should work just fine.
The code you are using includes card uids in byte but in the files they are in strings,what should i do?
Yes, I know, Just uncomment this line in the new code " Serial.println(CardID); " in order to get the IDs in string format. then copy them into the main code then upload it. you don't need to upload another code to get the IDs.
Contact me on my facebook page for more information.

Sorry cause I didn't explain it in the source code.
"Names" is the folder where the excel file will saved,
You have to create New Folder in the same folder where The Excel tool existed and name it "Names".
The Excel file Will save by any given name like "WorkNames". You can change it.
Here's the basic:
Serial.println(“SAVEWORKBOOKAS,Subfolder\Workbookname”);
In my case
Subfolder : Names
Workbookname : WorkNames

You're welcome.
As I understood from your question
You need to make the Excel save each entry to the same card. Thus, you have to modify the code in line 84 next statu[s]=1; add NumbCard[j] = 0;
and in line 105 next NumbCard[j] = 1; add statu[s]=0;

hi how can i get this to create multiple lines in excel so i don't have to disconnect and re connect each time i swipe the card/tag
sorry I didn't get your question.
ok when i present a tag to the reader i get one line of text in excel. this shows the parameters ive selected as in name, id ,time in and time out, i want to use this to track tooling coming in and out of my workshop from the shop floor. so i need one tag to write multiple lines in excel so i can save the sheet in the tooling folder and track who when and how long the tool has been on the shop floor. but i present one tag i get the time in and time out then i have to press the disconnect icon on plx-daq for the same tag to work again.
hope that makes more sense ?
how do i get it to repeat/reset and start a new line once tag is scanned a second time ?
Sorry for being late.
I recommended reading the Beginners Guide to PLX DAQ v2 (rev1) to figure out how the process is done, then you can make your own code simply with a particular parameter, bearing in mind you can't do any mathematical operation in the Excel tool automatically.
So If you interested in this project I'm going to publish a new version using the internet and nodeMCU as a professional project this weekend.
Stay close.
Cheers.
Hi
It's very urgent can you please help me ?
I am working on a project which is quite same as you'd shown in your video except that I have to import this excel data that is updating as I scan my rifd card to MATLAB
So, I wanted to know that can this excel file which is in communication with PLX-DAQ can be used for importing data to MATLAB
Yes, you can do that with Matlab. I think.
just use the xlsread function in your Matlab code
Bearing in mind you must modify the Arduino code to save the excel file once it detects new card and don't forget to determine where the excel file save.
