Object detection alarm using ultrasonic sensor and buzzer

In this video, we build an object detection alarm using an ultrasonic sensor and a buzzer with Arduino. This beginner-friendly robotics project helps you understand how distance sensing works and how an alarm can be triggered when an object comes close. We explain everything step by step so even first-time learners can follow along confidently. What you will learn in this video: • working principle of ultrasonic sensor • components used in object detection system • circuit connections explained simply • arduino code for distance measurement • triggering buzzer based on object distance • real time simulation and output This project is perfect for: • robotics beginners • school and college students • arduino learners • anyone interested in sensor based projects Next video will be a more advanced sensor based project. Comment Robot if you want the full robotics project series. Instagram ID - https://www.instagram.com/vstechhoriz... Linkdin - https://www.linkedin.com/notification...
