Automated Gate System designed with Arduino Uno, Ultrasonic Sensor, Relay and Switch

This project is about creating an automated gate system using an Arduino microcontroller. The system is designed to control the opening and closing of the gate through the use of an ultrasonic sensor, a relay, a servo motor, and buttons. The code provided incorporates the functionality of the gate opening when a car approaches it and also allows manual opening by pressing a button. The project is a simple yet effective demonstration of how microcontrollers like the Arduino can be used to automate physical systems and control various components such as relays, LEDs, and servo motors.
