Really useful video! Ty bro, you helped with project

[jason_man]

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

[janeksnaj]

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

[raghavan]

Any rfid program the connection will be same ah?

[Hiba-zy]

where doea the white colour pim get connected in audriuno borad

[ferbgaming]

Easy to understand bro pinsoke begineersn polum follow cheyyam😘

[longdang]

I don't see the code in your description. Can you give me a code link? your video is great and detailed.

[fero___]

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

[tanujkushalappa]

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?

[gianrodjundelarosa]

can you give the copy of your code in rfid basic example ?

[devdev]

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

[chiranjeevshubham]

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

[themangosteen]

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

[ramnaik]

hi.. I will great-full if u share the code please
