Arduino RFID Master Card Door lock System | Multiple Cards (MFRC522)

[@poltergeistducs2948]

Is there a limit how many you register??

[@fk_litos]

Good Project, but this with LCD and buzzer as you have done in other projects would be perfect, who knows one day make a video like that 😍 Many congratulations for the videos and thank you

[@titigafr]

hi, it would be good if the validated cards are saved in the EEPROM

[@husseinolivia2548]

Have you solved this issue, now I'm running my project and experiencing the same problem

Bro can u plz make a circuit which uses electricity and battery . electricity to charge battery and also to power so that it will work when no electricity like inverter

[@tatangkuswandaru8024]

thanks for the tutorial, sorry I downloaded Codes and Circuit Diagrams on the link you provided, but I can't extract the file with the name RFID_RC522_MasterCard_MultipleAccess.zip.

Can I install a push button switch with this RFID lock system so that the door can be opened from inside by pressing the button when needed? For this, please tell on which pin the switch should be connected.

[@zsoltzombory8553]

how many cards can it handle?

[@kostassomataridis3141]

As many you have

[@joshitoshi9835]

Thanks for the video, its really helpful. btw is it any feasible to use in real world scenario?

[@lelolasqq]

Hi, really nice video I did it and it works perfectly. Now I am wondering if it is possible to add a pushbutton to activate the relay. I want to put this on a door and I want one side activate the relay with the RFID and on the other side with the push button. If yes can you help me with the code. Thanks

[@firdoshdiakus4841]

Thanks for excellent tutorial I would like to know how many cards can be registered on this system?

Hi sir Can u combined this with finger print sensor lock 2 in 1 , one Arduino and 2 sensors (Rfid and fingerprint )?

Hello,love u from Pakistan

[@RidwanGhibran]

Hay Brother 🙏🙏 This is very useful for me who is still learning, I want to use the same function as you made .. but used for ON and OFF relays .. where should I change that part of the code ? maybe you want to help me 🙏 Thanks 🙏

Is the capacitor necessary? Plz answer Like you bro

[@t4tahmed427]

why di u use capacitor ? Do i really need it if i dont use any leds Thanks

[@christopherlawes9286]

Hi. Does this work on ESP32? Will it still work if power switches off then back on? Can you change master code if needed (like if you lose a card)?

[@therealuselesschannel]

1. Maybe you've to change the pins 2. Yes, it should 3. Load the programm new time

[@truyentranhaudio00]

Please program the servo controller. The first time the card rotates 180, the second time it returns to 0

[@breaker3533]

hi friends im new here. thinking to try this circuit, but have a small doubt can we use dc adaptor instead of batteries. if yes can someone guide how and what changes ned to be made to connect dc power adaptor. thanks in advance

Can you pls make qr code door. Thank you 😊

[@bushpilot4786]

Nice. Let me know, how to remove a lost RFID tag?

[@semperfi4418]

[@chimpofm]

Ok how to i add a button to to get out when inside. Not by shorting the relay. But by linking the button to accept uid function. Im using a motor controller. And a stepper. It works great without a button. But when i add it. The reader doesnt work or the button doesnt.

[@TechnoSAP]

Very nice video bhai

HOW TO ADD A PUSH BUTTON TO OPEN THE LOCK??

[@artcreator1764]

bro can you make object sensor with edge detector it will owsome

[@x-6790]

Check DIY builder video.u will get

[@Ganesh_vadlavalli]

Then how to open from inside the door can you explain

[@xavieraash]

This system as set up would be useful in a system that only needs to be opened from one side, like a cupboard. To enable exit when using on a door, the easiest option would be to wire a button between the two relay outputs (the door lock side of the relay) which will power the lock open while the button is pushed. Alternatively, you could place the rfid reader in a spot such that it can read the card on either side of the door, such as in a window.

Game and Art I am not sure why you do not have internet access, but I think that you should work on getting one first, because it is much easier way to learn. Absolutely FANTASTIC KZbin channel for Arduino beginners is Paul Mcworter’s Arduino lesson channel. Step by step, nothing left unexplained.
