Arduino Ultrasonic & Light Sensor Alarm Project | Buzzer Alert System
In this video, I built a simple Arduino alarm project using an Ultrasonic Sensor, Light Sensor, and a Buzzer. 🔔 Project Working: The buzzer turns ON when an object comes close to the ultrasonic sensor. The buzzer also turns ON when light is detected by the light sensor. If there is no object and no light, the buzzer stays OFF. 📦 ...
