Project Description: The project smart control management system in bridge is based on a bridge that collapsed a few months ago in Morbi, Gujarat. Due to the lack of a system, our team took the initiative to create a kind of system that manages crowds on the bridge. They used an Arduino Uno with two ultrasonic sensors, two servo motors, a breadboard, a buzzer, and finally, an LED as a smart hand band where visitors get from the entrance gate, When a person enters, they will receive a band from the entrance gate, and we will set the timer for 20 seconds for our project. After 20 seconds, the band will buzz the alarm and blink the led, indicating to security that it is time to exit. With this system, the crowd will be managed due to the time-bound system, and everyone will enjoy the walk across the bridge.
