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
