I need a code an arduino code that works with RFID RC522, 4 x4 Matrix Keypad, 2 LEDS and 1602 I2C LC Display

I am building a project for school security, So the user must use their ID to access the system. When access is granted then student has the options to choose 1 or 2 ... (1) Green LED = Safe (2) Red LED = Danger .. I am also thinking about adding a camera to the system but IDK how to wire that. But If I do the camera only turns on when option 2 is picked.

RFID - verify user ID

4 x4 Matrix Keypad - Second security input only if the red LED IS on

1602 I2C LC Display - Display the result to show access granted and access decline

My pins are for RFID

3.3V to 3.3V

RST to digital 9

GND to GND

MISO to digital 11

MIST to digital 12

SCK to digital 13

SOA to digital 10

My pins for LCD

GND to GND

5V to 5V

SCL to A5

SDA to A4
