[@MichaelKyeremeh-hj7up]

I'm a student who learn how to program the RFID reader and get the meaning of the coding and I don't understand what you have been written here "if (! mfrc522_PICC_IsNewCardPresent())
And I don't understand why you bring the exclamation mark before the mfrc522

[@annadmitrenko3838]

Really useful video! Ty bro, you helped with project

[@lj1031]

Where can I find the code?

[@jason_man]

How did you light up leds without a resistor wouldnt it burn with arduino?

[@ZenoModiff]

Nope it won't burn

[@janeksnaj]

can you make better building instruction it doesn't work because of "WARNING: Communication failure, is the MFRC522 properly connected?"

[@elijahnjuguna7435]

connect Vcc to 3.3v and GND to ground If you are using the Dump info code connect RST pin to 9 and ss pin to 10 for arduino mega2560

[@raghavan6399]

Any rfid program the connection will be same ah?

[@tanujkushalappa2067]

LiquidCrystal_I2C.h: No such file or directory
Even after uploading the library which was given in the link, i'm getting an error.
Can you please help me out with this?

[@ZenoModiff]

I haven't given i2c Library brother it's the RFID library

If you have any questions ping me on [e-mail]

[@adrianemig8196]

did you find a solution, i have the same problem

[@allanndungu360]

The code he has typed uses LCD screen for display. But in the video there is no lcd connected so no need to include liquid crystal library. I edited the code to remove the lcd code. Use this instead:
#include
#include

#define SS_PIN 10
#define RST_PIN 9
#define LED_G 5
#define LED_R 4
MFRC522 mfrc522(SS_PIN, RST_PIN);

void setup()
{
SPI.begin();
mfrc522.PCD_Init();
pinMode(LED_G, OUTPUT);
pinMode(LED_R, OUTPUT);

}
void loop()
{
// Look for new cards
if ( ! mfrc522.PICC_IsNewCardPresent())
{
return;
}
// Select one of the cards
if ( ! mfrc522.PICC_ReadCardSerial())
{
return;
}
String content= "";
byte letter;
for (byte i = 0; i < mfrc522.uid.size; i++)
{

content.concat(String(mfrc522.uid.uidByte[i] < 0x10 ? " 0" : " "));
content.concat(String(mfrc522.uid.uidByte[i], HEX));
}
content.toUpperCase();
if (content.substring(1) == "46 44 54 73")
{
digitalWrite(LED_G, HIGH);
delay(2000);
digitalWrite(LED_G, LOW);
delay(2000);
}

else {
digitalWrite(LED_R, HIGH);
delay(2000);
digitalWrite(LED_R, LOW);
delay(2000);
}
}

[@fero___3005]

can i use 5v motor gfor output any changes in code

[@ZenoModiff]

No change in code but insted of relay use PNP type transistor and connect to the digital pine where we have wire the relay that's all no change in code

[@ferbgaming9529]

Easy to understand bro pinsoke begineersn polum follow cheyyam😘

[@ZenoModiff]

Thanks for you Comment bro ❤️

Can RFID reader scan a NFC tag ? Please reply 🙏🙏🙏🙏🙏🙏

YE

[@AlexandreAdoukonou]

Code Arduino

[@devdev5637]

SIR CODE AND ALL UPLOADED GREEN LIGHT WORKING BUT RED LIGHT IT'S NOT BLINKING CHECK EVERYTHING WIRE, LED, WHAT TO NEXT?? WHAT CAN BE THE PROBLEM

[@ZenoModiff]

Did u use jumper cables to connect the circuit if yes please check the continuity of the wires that will solve the issue

[@devdev5637]

@@ZenoModiff i will check once again and let you know thank you

[@devdev5637]

sir did everything possible changed jumper wires changed led but the access denied one is not working if code attached the light is blinking but random rfid card no light is blinking i.e red

[@janstudio321]

CAN I GET THIS CODE
2:41

[@garvit_panwar]

can we use arduino r3

[@ZenoModiff]

Yes you can use just change the board name while uploading

[@bhavya165]

thank you may god bless you sir

[@themangosteen9144]

Do not connect to 5v it will burn RFID Module, its supposed to be 3.3
