- In previous video I have show you how to use RC522 RFID reader with arduino, now it's time to show you how to use this with an nodeMCU. Like Previous tutorial, this tutorial will be very easy too.

I don't know how to thank you. You saved me a lot of time
Thankkkk youuuuuuuu
thanks you a lot mister !!! Have a great day you made my week
thank for your description, now i know
Bro THANK YOU SO MUCH !!!!!!!
I like and subscribed too :D
Thank you so much!
Great and simple video
Thank you so much
Hello, thanks for the video but my RFID only scan up to 9 digit, where it should be 10 digit, can you help me with that
pls make use of the I2C protocol the rfid reader can do SPI but also I2C because I2C is easier pls use it
As per your tutorial I tried this project and used laptop power, tried with 3 mfrc522 board but on each case the RFID on-board led does not glow. I have checked the connections several times and getting output voltage from nodemcu 3.3v as per the multimeter. Can you guide me where is the problem?
when 3.3V and GND connected to NodeMCU should no problem. Just connect those two wires first. Are you sure the wiring is connected and use the same RFID reader as mine?
what type jumper wire you use and what type cables you use ??
Hi, great video. Is it possible to shut off RFID reader when esp turn into deep sleep?
Maybe that's possible, you can use a switch. Put the switch off when it go to sleep
te amo mlkk
good video keep making video :D
i suggest to make video all about corona or just click bait of corona topic, i think it is very useful like project about non contact desinfectant. I think you need to for your cowroking space. just suggestion
*too
yes im planning on that
@@miliohm i looking forward to that
thanks
but how to open this tab in separate
i have done exactly the same way , connections , the code as well , but the in the serial monitor the tag id is not displaying ...!
Me too, why that happening?
hi can i change my rfid number with this? i mean can i edit my rfid card?
please make 10 chanel current and voltage read from 10 solar pane and monitor blynk app in mobile esp32
all the circuit and codes has executed successfully but the problem is the rfid doesn't save in database, how can we solve this?
Hi
Can I increase the range of this module upto 1meter?
You should buy the long range type
it fun,nice video.
esp32cam QR code reader can you make a video too.
Does it also works with Mifare Desfire cards?
it should work with any cards with a 13.56 MHz frequency
hello, i do like you do but every time i had this "hard resetting via rst pin" thing. how can i fix it? please help. itried the online solutionsa but it didnt work
Where did you get hard resetting via rst pin?
@@miliohm after upload the cod
@@miliohm and it isn!t read my tag,i tried change the baudrate and frequency but nothing happened
Double check the wiring, sometimes it just caused by wrong pins
@@miliohm i chechked millon times, im trying to work this sensor like 4 days :( thank you
good, how to add more tag? i test with "," not work
you should add else if. so the else if will take care more tags.
For example if(tag=="1"){} else if(tag=="2"){} and so on
if (tag == "123456789" or tag == "987654321")
or
if (tag == "123456789" || tag == "987654321")
not working, while the light shows in both the RFID module and nodemcu. Even tried it with arduino still it is not showing any output on serial monitor
same problem..
Did you fix it?
Hello
I have this problem
'D3' was not declared in this scope
Make sure your board is nodemcu
@@miliohm Well the problem is when I compile the code
@@jesserelles1937 yes, are you sure your board is nodemcu?
@@miliohm yes..
@@jesserelles1937 Found Any solution?
know i can make door like amazing spider man using rfid to unlock the door
what is the name for the wire
Malem to male
Compilation error: 'D3' was not declared in this scope help me pls
Make sure you choose NodeMCU as your board
how to add more card?
You just need to add else if with another card number
@@miliohm can you write that piece of code here to add a new card? Thank you
@@hypnomediahm373 I already add the code at the link. Check it.
sir card id is not displaying on seriol monitor
Make sure the baudrate is correct, then after opening serial monitor. Reset the nodemcu by pressing button on the board
@@miliohm still no response sir
i have bought 2 rfid sensors and checking on both still not working sir
@@varunkumar-4017 have u fix the problem? I have the same problem
what name hardware sound ?
Did you mean buzzer?
celui-ci etait genial.
Merci
Buen video bro, pero no me salio mi tren :( chin
i am trying to do like you but nothing work i don not know why
Double check the wiring. Did the sketch uploaded successfully?
@@miliohm i upload your code but nothing appear on serial monitor i test rfid with arduino and work successfuly but not work with nodemcu
@@adhamshrabh4588 have you fix the problem? I have the same problem
His way of speaking is like shincan (hindi dub)
can rc522 write ?
Sure
it doesnt work for me :(
Can you help me please ..
Check the wiring diagram, make sure every cable are correct
@@miliohm everything is as yours... but when run serial monitor is blank... nothing on it
@@HimaSpirit try resetting the nodemcu after opening serial monitor
@@miliohm i did it, but there are no changes
what is the problem with that?
Links to code is broken
still working here
Pak
Ya
@@miliohm pak mau tanya, library Arduino sama esp8266 beda atau sama?
