<html><body>This Arduino-based Motion-Tracking Turret is a smart robotic system that detects nearby movement and reacts like a futuristic sentry. Using the HC-SR04 ultrasonic sensor, it continuously scans its surroundings. When a target is detected within 30 cm, the turret locks onto it with a servo motor, and a combination of laser diode, LED, and buzzer activates for visual and audio feedback.The laser stays on during idle scanning, but switches to blinking mode when a target is identified, perfectly synchronized with the buzzer. This gives the impression of a “locked-on” alert system. The turret automatically resumes scanning once the object moves out of range. Built with Arduino UNO R4 Minima and commonly available components, this project merges creative automation with practical electronics.Ideal for those exploring robotics, motion detection, embedded systems, or DIY tech, this turret is a hands-on way to learn and impress!</body></html>
