Intelligent access control system

Components:
STM32F103C8T6 minimum system board
, 12V to 5V step-down module,
5V to 3.3V module
, OLED 0.96-inch four-pin
RC552 module,
AS608 fingerprint module,
16x6*5*5 tactile switch matrix keyboard
, buzzer module,
130 DC motor ,
ASRPRO development board with microphone (not the core board),
DC005 female connector (for lithium battery),
SS-12D10L5 toggle switch,
one 1k through-hole and surface mount resistor, and LEDs (0805 surface mount package, used for lighting simulation and power indicator).
 
Functions:
Access control:
fingerprint, RFID card support login, registration, and deletion modes.
Passwords only support registration and login.
Matrix keyboard: * key for login, # key for registration password, = key for confirmation password, other keys can be freely entered. Passwords support a maximum of 6 digits.
Display and feedback:
The OLED displays the current mode and on/off status in real time, and indicates success or failure.
A buzzer will sound a long response after the access control unlocks; a buzzer will sound a rapid error if various errors occur (login failure, registration while not logged in, deletion).
ASRPRO:
Customize voice recognition prompts using the Tianwen Block graphical programming software. These prompts control the switching of ID card, fingerprint, and password lock modes. After opening the door, lights and motors can be turned on or off via voice. After voice recognition, corresponding commands are sent to the STM32 via serial port. The serial port callback function switches modes and statuses according to the commands. (
