Automatic Door Opening System
An Automatic Door System using Arduino, an ultrasonic sensor, and a servo motor that detects an approaching object and opens the door automatically.
Description
The Automatic Door System is designed to open and close a door automatically based on the detection of an object or person using an ultrasonic sensor. The ultrasonic sensor measures the distance of an approaching object, and when the object is detected within a specific range (e.g., 15 cm), the Arduino sends a signal to the servo motor to open the door. After a set time or when the object moves away, the servo motor closes the door automatically.

The Conveyor Belt Object Counter using LDR and 7-Segment Display with the 8051 microcontroller is designed to count objects passing in front of an LDR (Light Dependent Resistor) sensor. The system works by detecting light interruptions when an object crosses the sensor, causing a change in the LDR’s resistance. The microcontroller processes this change and increments an object count. The count is then displayed on a 7-segment display.
