Security Alarm Using Arduino Nano & Ultrasonic Sensor 🔔 | Simple Project

In this video, I have made a Security Alarm System using Arduino Nano and an Ultrasonic Sensor. WIRING = ----------------------------------------------------------------- ultrasonic VCC=5V TRIG=D2 ECHO=D3 GND=GND buzzer POSITIVE(+)=D4 NEGITIVE(-)=GND ----------------------------------------------------------------- CODE = SORRY I CANT UPLOAD LINK YET BUT PASTE THE WIRING IN CHATGPT AND TELL HIM TO MAKE CODE FOR SECURITY ALARM AND HE WILL MAKE IT. ------------------------------------------------------------------------------------------ This project detects motion or intrusion using the ultrasonic sensor and triggers an alarm when someone comes near the system. It is simple, low-cost, and perfect for beginners, school projects, and electronics enthusiasts. 🔧 Components Used: Arduino Nano Ultrasonic Sensor (HC-SR04) Buzzer Breadboard Jumper Wires 📌 Applications: Home security system Door intrusion alarm School & college mini project Beginner Arduino project 👍 If you like this project, don’t forget to LIKE 👍, SHARE 📤, and SUBSCRIBE 🔔 for more Arduino and electronics projects. arduino security alarm ultrasonic sensor alarm arduino nano project security alarm using arduino ultrasonic sensor arduino arduino nano ultrasonic sensor arduino projects for beginners electronics projects arduino mini project school arduino project security system using arduino diy security alarm arduino buzzer alarm
