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

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:

The diagram with the LCD driver and without it:

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.

Hi everyone. Recently, There was a problem in the Arduino code while detecting the cards and read many cards as the same. So I tried to fix that problem and everything went well. If you're interested, now the code is available to download from this link: github.com/InfinityWorldHI/RFID_Excel If you want to ask about something you can email me: " [e-mail] " or send a message on my facebook page: facebook.com/ElectronicsTechHaIs/ Stay close.

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?

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?

[@ElectronicsTechHaIs]

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.

[@addilalatif4410]

I see, After opening the Excel sheet you have to allow running the macro (yellow warning message at the top).

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

[@ElectronicsTechHaIs]

You're welcome. first, check out this video: kzbin.info/www/bejne/mom9mnmua7eDbNU 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.

[@ElectronicsTechHaIs]

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, kzbin.info/www/bejne/mom9mnmua7eDbNU let me know if you faced any issues.

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.

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.
