RFID Security System With LCD

RFID Security System with LCD
This experiment is to create a security system with RFID and LCD. If we place the correct access card in the RFID module, the buzzer will turn on and the LCD will display as 'Authorized Access'. If we place the wrong access card in the RFID module, it will display 'Access Denied' in the LCD.
Required Components
==================
1. Arduino UNO
2. RFID Module
3. LCD Display
4. I2C Converter.
5. Buzzer
6. A to B USB Cable
7. Male to Male Jumper Wires

Finally a project that works. Thanks

[@TechTrendsShameer]

You're welcome!

[@sushmithasenthilvelan2429]

Which tool did you use to draw the circuit diagram ?

[@TechTrendsShameer]

Fritzing.

[@rohanpthomas675]

sir on the serial monitor it shows the access denied and access permissed commands but ain't no output is displayed on the lcd display.checked the circuit and what could be the possible reasons chances of this issue (all new components and lcd display is taking the supply and backlight is on.)

[@shiyamsundar9985]

Hello sir firmware error came
And it is not scan the code give some solution

[@TechTrendsShameer]

remove and reconnect again and try.

[@hasiniamarathilaka4903]

Sir, I'm interested your this video and i have no idea about this c code. Can you e-mail that c code to me??

[@TechTrendsShameer]

I have added the source code in the description. Can you please check ?

[@hasiniamarathilaka4903]

@@TechTrendsShameer oh I thought I would need separate codes.. ok thank you very much

[@TechTrendsShameer]

If you are facing any problem in the output, let me know
