- MFRC522 is maybe cheapest RFID Reader that we can found now. It uses 13.56 MHz frequency And it is also easy to use. We can easily interfaced this reader with arduino or raspberry. This video can be the simplest tutorial on how to use this RFID reader with arduino.

Thank you for the great video! Super easy to follow along!!
Thanks!
hi may i ask is there a way to use the tag to turn on a switch and the switch stay on until the unit it powered off / rebooted. so the tag closes the switch and no matter if the tag comes into contact again once the switch is on it has no effect.
I checked many videos, all didn't work. Yours worked! Thanks
Good to know it helped!
the RFID library make it very very easy thanks man for this tuto
Sure!
thanks for the video. helped me get an A in class. thank you!
Happy to hear that! 😀
Hello Sir, can you teach us how to interface AS608 with esp32? Thank you.
Do you know how can reuse the pins of an arduino? I have another lcd screen that I’d like to use on the same board. Some sort of switch will probably help solve my problem as I don’t need them both working at the same time. Would love any ideas
What does halting the rfid mean, and what does the init method do? And what is serNum is that an array?
helo bro how to connect 2 rfid sensors in a arduino plz make a programe
I've downloaded and included both RFID libraries copied the code into Arduino, but getting the error message 'class RFID has no member named 'isCard'
Thanks for this tutorial. Worked ok.
Need help bro.....everything is correct but rfid sensor doesnt recognise rfid card tag ...whenver i try to read the rfid card in COM3 its coming like this..." ????.???...u..??..??." What is this bro ??
i need help. im trying to add the rfid library from manage librarys but how do i get to my ribrary and inset it as its showing other peoples files and telling me to download it. been at it for hours and i stg amma scream
My compliments for your great explanation and how the code works. Thanks for sharing and wish you the best of luck with your projects.
Thank you!
I have an one daut about this ...
how get card numbers in new arduino ide
Hope u add relay to this project, good job.. thanx
Great Job!
why does my reader cannot detect my card
bro how do it in an excel sheet
Hey bro. I'm getting following error.. Plz help
Firmware version : 0x0 = (unknown)
Warning : communication failure, is mfrc522 properly connected?
Make sure your wiring is correct. Should no problem
where is the SPI library
Is it possible to customize the sound for each rfid card ?
Yeah, but you need to organize the sound based on number or something
help me. all the wiring are great. the code uploaded. the serial monitor pops up and said "Starting the RFID Reader..." but when i put my card/tag on the rfid sensor, there's nothing. there's no id pops up on the serial monitor. what could be the problem here?
Same problem here, anyone?
@@GWS-schouwen same problem
@@bizarro4587 same do you get any solution
@@bizarro4587 because i need to sumbit project
Why whenever I upload the script it says that the #include has no such file directory? Even when I do copy and paste the code the same problem is there. Could this just be because we have different versions or the IDE?
RFIDKeyTest:2:10: fatal error: RFID.h: No such file or directory

This tutorial uses 2 libraries. Make sure you add the second library too
hello there... i am really need of help right now.... how can i code the RFID tag so it can perform addition operation... i mean like one card reads value of 3 and another card reads value of 4 so i want to make an addition operation...can someone help me
If you set the RFID number of a card equal to a number and the same for another, you should just be able to code it so that when the specific RFID numbers are scanned, it adds the corresponding numbers
Hello Sir
thanks for this great video. I need help now. The RFID sensor does not recognize the RFID card. The wiring connection has been checked and the programming is all correct but does not work. I dont know Why!!
Nothing detected? Did you use the right card? The cards that come with the reader
@@miliohm Same with mine, nothing is detected. I used the same card that comes with the reader
mine too
same here
mine says: Class RFID has no member named isCard()
Thanks bro
love it
Can this be used to detect a moving vehicle?
I don't think so, the distance is only about 1cm
downloaded the libraries, checked the wiring, using arduino uno, compiled completed, it is printing "starting the rfid reader" but it is not reading the card.
That is exactly what’s happening to me
@@erickwhatcott6016 I noticed that some RFID readers have bad quality. Out of 5 you get 1 to work. Better buy from a trustworthy supplier.
RDM6300 with arduino! pleas
please can it read debit or credit card Number
It is for RFID/NFC card. I don't think the debit or credit card number is stored on NFC. CMIIW
is that Male to Male wires ????
Yes
Is there any library for the RC522 in c++? I really need it to work with the STM32 microcontroller on Nucleo board F429ZI.
If anyone knows about the library, I will be more than grateful to you.
You explained it real good

Getting this error, I think I should try installing Library from the library manager. Which library for RFID do I install?
nevermind, I fixed it
How did you fix it I have the same issue
You need two libraries
Nvm I fixed it thank you for the video
@@miliohm What other library do i need to install?
I’m getting a error message for line 2 it is telling me there is no such file or directory for RFID.h
that means you don't have the library. add the library first
@@miliohm I downloaded it but don’t know how to apply it to the code
@@landevi8638 the easiest way is using manage libraries on tools menu. then search for your library.
Or you can download it manually and copy the library folder to your arduino library folder. Usually on documents/arduino/libraries
@@miliohm which library because I am getting the same error
@@brianngondo3771 second library. Named RFID
Can u please tell me the name of Arduino???
Is it Arduino Uno???
yes of course, it's arduino uno. chinese one, and smd one
@@miliohm I am doing bus ticketing system with RFID reader project, can u please guide me😊, can u please make a video on that 😊
I need help it won't detect card
what's on the serial monitor?
I've Rewired this 10 times and it says it starting but it doesn't accept the card
same but this creator not helping genuine creator
hello sir!
i request you to make a video regarding the same RFID with passive sensor
like have a parking system and when car or bike enters the entry of that tag will be made in the computer.
aslo the sensor works at a range of few meters so i d like to see how to programme(read a tag) from certain distance.
Yeah, maybe in next video. But if you want long range sensor. You totally need different RFID reader. You can buy long range RFID reader.
makasih

it wont recognize the RFID.h file
its says:

Did you already install 2 libraries?
@@miliohm yes i installed both it recognizes the SPI.h but not RFID.h

Why rfid reader not detects rfid card
pls ur link not active
It's still active

@@sherifghaly9746 what it said? Because here it is still running properly
good video, thanks :D
'class RFID' has no member named 'isCard'; did you mean 'findCard'?
same...did you solve it?

it shows me an error:

it is likely you didn't install both libraries. This sketch needs two libraries.
@@miliohm so i need to create 2 files? Or i need to search them?
