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

#include <SPI.h>
#include <MFRC522.h>
#include <Servo.h>

#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 ( !
{
return;
}
// Select one of the cards
if ( !
{
return;
}
//Show UID on serial monitor
Serial.print("UID tag :");
String content= "";
byte letter;
for (byte i = 0; i < mfrc522.uid.size; i++)
{
< 0x10 ? " 0" : " ");
Serial.print(mfrc522.uid.uidByte[i], HEX);

content.concat(String(mfrc522.uid.uidByte[i], HEX));
}
Serial.println();
Serial.print("Message : ");
content.toUpperCase();
if (content.substring(1) == "B3 05 D4 11") //change here the UID of the card/cards that you want to give access
{
Serial.println("Authorized access");
Serial.println();
digitalWrite(6, HIGH);
delay(200);
digitalWrite(6, LOW);
myServo.write(180); // Rotate the servo to 180 degrees
delay(3000); // Wait for 3 seconds
myServo.write(0); // Rotate the servo back to 0 degrees
}
else

Serial.println(" Access denied");
Serial.println();

thanks yyar bhai aur bhi nayi video banatai raho


its my school project and i got 1 position thanks once again

[pault]

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

[pritammondal]

Sir your video is osm...to I Am your Big fain....

[chubielester]

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

[asep]

Makasih banget codingannya buat kerjain tugas

[amitabheer]

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!

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

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

[MsLuis]

How can I make the circuit open with both cards?

[bczin]

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

[andriharii]

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?

[electronichacks]

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 🙏🙏🙏

[luzdollylopezguerra]

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

[leonardcainguitan]

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

[Assassxndev]

can you make a security system with akeypad and rfid

[ATLTraveler]

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.

[arceditor]

Give direct link for code and circuit diagram

[felconero]

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
