Simple RFID control servo motor for smart door lock system using arduino 

A pesar de que parezca tanto cablerio es realmente sencillo, lo arme en unos cuantos minutos. Excelente video!

#include #include #include #define SS_PIN 10 #define RST_PIN 9 #define SERVO_PIN 8 // Define the servo pin MFRC522 mfrc522(SS_PIN, RST_PIN); // Create MFRC522 instance. Servo myServo; // Create servo object to control the SG90 void setup() { pinMode(7, OUTPUT); pinMode(6, OUTPUT); myServo.attach(SERVO_PIN); // Attach the servo on pin 8 to the servo object Serial.begin(9600); // Initiate a serial communication SPI.begin(); // Initiate SPI bus mfrc522.PCD_Init(); // Initiate MFRC522 Serial.println("Approximate your card to the reader..."); Serial.println(); } void loop() { // Look for new cards if ( ! mfrc522.PICC_IsNewCardPresent()) { return; } // Select one of the cards if ( ! mfrc522.PICC_ReadCardSerial()) { return; } //Show UID on serial monitor Serial.print("UID tag :"); String content= ""; byte letter; for (byte i = 0; i < mfrc522.uid.size; i++) { Serial.print(mfrc522.uid.uidByte[i] < 0x10 ? " 0" : " "); Serial.print(mfrc522.uid.uidByte[i], HEX); content.concat(String(mfrc522.uid.uidByte[i] < 0x10 ?

Thank you very much for this video. My project works now. I appreciate it. Great video.

Thank you so much Love from PH dude you did well and my project works... 🔥

thanks yyar bhai aur bhi nayi video banatai raho its my school project and i got 1 position thanks once again

Sir your video is osm...to good.......👨🏼‍🔧 I Am your Big fain....

Superliked!!! I would like to thank you for your informative video. You illustrated all that therein and I could build my security access in less than an hour. I want to add a LCD display to show few information as under: 1."Authorized" message with Name (attached to Card ID) on Successful login 2."You are not authorized" message on wrong cards 3."Use your card" on Idle mode 4.Other messages related to Card Hope to get reply from you asap. I appreciate your time and efforts.Keep it up!

Thanks a lot brother..................its very useful

Thank you bro it worked for me

I have been try this , it's work. Thank you very much

Thanks for the best video

Excellent work bro keep it up 😘

Makasih banget codingannya buat kerjain tugas

its very very helpfull

LEGAL!

Buen día. En este proyecto el servo no funciona. Sólo funciona un led y el buzer.

What’s the music? 5:27 Bty very nice video!

Worked amazing video

Why I can’t used with battery 9v or 12v ? Please tell me how should I do ❤

How can I make the circuit open with both cards?

Sooo good

bro, why my arduino IDE cant detect the rfid cant connect When I execute it, I get the message: Firmware Version: 0x0 = (unknown) WARNING: Communication failure, is the MFRC522 properly connected? Scan PICC to see UID, SAK, type, and data blocks... I have re-checked the connections a thousand time but it's not working, the pins are connected as the example says to, and the LED D1 is on (red). Do you can help me?

sağol

Thanks

Excelente gracias mi hermano

That servo motor probably isnt strong enough to throw a deadbolt. Any lock that could be thrown by that tiny servo could be ripped off so easily, but it's a cool theoretical project.

cool it worked thanks

Sir can I use this coding for arduino uno R3 in mobile phone in arduino Droid app please fast reply I am making this for my school submission 🙏🙏🙏

It's working thank u

Good day sir. Did you try already 2 rfid at thesame time

How about by using wemos d1? When i touch the card to the sensor, both led will off and after that both led are on at the same time. Can you help me to fixed it. ASAP thank you

Give direct link for code and circuit diagram

why, when im using this two types of cards, all of them showing that the card is correct

Room k andar too rfid tag use Nahi Kar sakte Bhar aane k liye too kese Bhar nikle ga koi

can you make a security system with akeypad and rfid

Any ways it's nice bro😘

Thnx for this

can someone help me? Firmware Version: 0xF0 = (unknown) Scan PICC to see UID, SAK, type, and data blocks... this is the message in serial monitor

The lock is not moving everything else works.Help Me

No me lee la tarjeta ni el TAG, alguien sabe que hacer...

Error: 13 INTERNAL: Library install failed: moving extracted archive to destination dir: Library MFRC522 is already installed, but with a different version: MFRC522@1.3.6 . i found this error , anyone can help me plzz its urgent ,

Why i cant use 9v battery?

Please solve your code

exit status 1, error compiling for arduino/genuino uno help me how to fix this error

Sir please give me a code link

Firmware Version: 0x0 = (unknown) WARNING: Communication failure, is the MFRC522 properly connected? Scan PICC to see UID, SAK, type, and data blocks...

Bhai esh Mai Banda andar Jane k bad kese Bhar Aaye ga reset button too kaam hi Nahi karta code mai

Sir mujhe iska circuit diagram aur code chahie

Bro Can you help me to add multiple card

Sir please provide cricuit diagram

Hi can you make it using arduino nano

Can u leave a link for code

sir please help me ;( it says ARNING: Communication failure, is the MFRC522 properly connected?

How to get out of the room?

Please remove autolocking

it is showing errors

Code

SHOW.

Cold??????????¿?¿??¿?!¿

Background music ta valo hy ni

guyssssssssssssssssssssssssssssssssssssssssssssssssssssss helppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppp

i wont your code

making soup in the background

bro can u help me now !!! im cant use code MFRC522.h Arduino: 1.8.18 (Windows 10), Board: "Arduino Uno" Arduino-Security-Access-Lock-RFID-MFRC522:7:10: fatal error: MFRC522.h: No such file or directory #include ^~~~~~~~~~~ compilation terminated. exit status 1 MFRC522.h: No such file or directory This report would have more information with "Show verbose output during compilation" option enabled in File -> Preferences. pls help me!!
