Password Based Door security system | Mini Project Idea | STM Controller | STM Project | HAL Library
Hello,
In this video we have interfaced keypad, LCD and stepper motor with stm32 controller. We control the door operations by entering the password using the keypad. The door opens only when correct password is entered. Door opens for some time, let the person enters and then closes back. The door opening and closing are controlled by stepper motor. The simple interface can be used in many projects.
