How to use RFID with Arduino | How to use the RC522 RFID module with an Arduino - Tutorial

[@evoiboi69]

this did work, my rfid reader did read a card
but how did you put led's without showing them
i dont want to stare at a serial monitor all day just to see if my card declined

[@jeffbowyer4576]

Concise and informative. Exactly how I like tutorial videos.

[@electronicGURU]

thank you

[@User-hg9re]

It disnt work. I connect rfid reader directly to arduino and it doesnt work. Should I use resistor or something and where should I use it? I saw something on forums but its not shown in your diagram

[@noureenashameer6826]

I am buying Arduino RFID reader kit this weekend 🎉

[@SartajSaif]

My error please reply me,
01:47:20.586 -> Firmware Version: 0x0 = (unknown)
01:47:20.586 -> WARNING: Communication failure, is the MFRC522 properly connected?
01:47:20.623 -> Scan PICC to see UID, SAK, type, and data blocks...

[@electronicGURU]

check your connection/wiring

[@AbdulMoizAdeel-www]

so you should connect directly to arduino instead of motherboard and make sure connections are not loose if your rfid module is not working

[@ravibharti3433]

Sir I bought rfid card from Delhi but cards not working. We not found UID I'd.

[@ravibharti3433]

@@electronicGURU rfid card cannot be scanned.

[@ravibharti3433]

show approximate your card to the reader on the serial monitor

[@RandomEditsCo]

How far can the sensor get the key

[@YashJain-qh5tn]

less than 1cm

[@YashJain-qh5tn]

it have very less range to detect and we can't increase it

[@electronicGURU]

yes thats correct

[@iswaryakuchimanchi9176]

Hello. My module is not reading the cards. And it says that firmware is unknown.please help me resolve this problem for our project.please

how to use RFID with stc 8081 ?

[@kingcreatez4827]

hi can i have a schematic for the connections from rfid module to arduino pls

[@electronicGURU]

i already mentioned it in video ? right? what needs to be connected where?

sorry i Don't have it now , i usually delete it all after video publishing. please take a screenshot from video.

Hi sir! Your video is very informative! so is it possible to do this with TCP/IP?

Bhai maine sub kuch kia bar bar connection ki par wo card ka uid hiii nahi de raha hai

[@Pragadeeshwaran.S]

Thank you so much

[@PradeepKumar-zb1dh]

Great video once again 😃

[@talhaislam4848]

Please share the code with more than 1 RFid access. or share link if there is any video thank.

[@michalvydareny5284]

here you go pal:
just change if condition with authorized access
if (content.substring(1) == "(1st rfid tag)" || content.substring(1) == "(2nd rfid tag)"

[@girishpanchal9072]

Hi
Can I increase the range of this module upto 1meter?

[@matthewfreeman6187]

Umm no its alot more complicated than that

Most probably it is a connection error try pressing it with your finger or push it a little to the front or back while trying to scan

Is this mean my RFID broken?
