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.

An Electronic Coin Toss circuit is an electronic version of the classic coin flip — often used to make quick decisions, settle disputes, or play games. It mimics the randomness of a real coin toss using digital logic or a microcontroller to generate a pseudo-random result and display it using LEDs or a text display (e.g., “Heads” or “Tails”).
