Concise and informative. Exactly how I like tutorial videos.

[@electronicGURU]

thank you

[@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

[@LeveluplegendXLLAlt]

best rfid video

I am buying Arduino RFID reader kit this weekend 🎉

[@Pragadeeshwaran.S]

Thank you so much

[@kevilysoled5302]

thankyou very much buddy!

[@Gumballation]

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

[@PradeepKumar-zb1dh]

Great video once again 😃

[@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

[@VocesSinFronterass]

I have the same problem

[@incognitowriter2240]

Any solution?

Thanks

your welcome brother

Very good

[@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?

[@kingcreatez4827]

@@electronicGURU yeh you did thanks, but can you send a png file of it pls?

[@electronicGURU]

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

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

[@ravibharti3433]

show approximate your card to the reader on the serial monitor

[@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

[@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

[@Hnzm21]

he is not reading my card

[@incognitowriter2240]

Any solution?

[@mreazen609]

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

wrong info shown in video you code doesn't show sector data

Sir I have a doubt ,,How we add the information in RFID tag

Yo there is no info

Can you help me it says firmware version unknown and its says warning communication failure on Comm 5

[@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)"

[@sumitabiswas5099]

Nice......

[@user-vi9ky3nb9l]

Firmware Version : 0×0 = (unknown)
Is this mean my RFID broken?

[@VocesSinFronterass]

Same problem

[@aryanprakash7371]

can be broken but firmware can be updated using GiT

Umm no its alot more complicated than that
