Explore the realm of smart door automation with our “Automated Door Control System with LCD Feedback.” This Arduino-based project incorporates a servo motor, LED indicator, and a liquid crystal display (LCD) to create an intelligent door management system.
A sensor detects the door state, and based on the input, the servo motor adjusts the door position. Simultaneously, an LED provides visual feedback, and the LCD displays dynamic messages like “DOOR OPEN” or “DOOR CLOSE.” The system ensures seamless control and status visualization, adding a layer of sophistication to conventional door mechanisms.
The hardware setup involves connecting the LCD to specific digital pins (12, 11, 5, 4, 3, 2), the servo motor to pin 7, an LED to pin 6, and a sensor to pin 8. The servo motor controls the door movement, the LED acts as a visual indicator, and the sensor determines the door state. Power the LCD and servo motor as per their specifications, and connect the sensor, LED, and Arduino to a common ground.
