- Power Supply:Power the STM32F103C6T6, servo motor, RFID reader module, and LCD display with a 5V power supply.
Write a program for the STM32F103C6T6 to control the servo motor and communicate with the RFID reader module and LCD display. Implement logic to read RFID cards or tags, verify access permissions, and control the servo motor to lock or unlock the door.
TestingUpload the program to the STM32F103C6T6 and power up the circuit. Test the smart door lock system by presenting RFID cards or tags to the RFID reader module. Verify that the system responds correctly by locking or unlocking the door and displaying the status on the LCD display.
ConclusionCreating a smart door lock system with the STM32F103C6T6 demonstrates its capabilities in implementing secure electronic access control systems. This project can be further enhanced with additional features such as remote access control or integration with a mobile app for smart home automation.
