How to make a Security System with Ultrasonic Sensor and Arduino

Описание: Build a distance sensitive security system with ultrasonic sensor and Arduino board.

This project is an ultrasonic sensor based alarm. It is distance sensitive so the speed of the buzzer depends upon how close or far the object is. If the object is near then the buzzer beeps faster and if it far then the buzzer beeps slowly.

Components Used:
1. Arduino Uno - https://amzn.to/3JsbMOw
