DIY Obstacle Avoiding Robot Using Arduino DIY Obstacle Avoiding Robot Using Arduino This project creates an intelligent obstacle avoiding robot that autonomously navigates through environments while avoiding obstacles. The robot uses an ultrasonic sensor to detect objects and a servo motor to scan the surroundings, making smart decisions about which direction to move. How the Robot Works Ultrasonic Sensor continuously measures distance to obstacles ahead When obstacle is detected within 25cm: Robot stops and assesses the environment SG90 Servo Motor rotates the ultrasonic sensor to scan left and right directions Robot compares left and right side distances to choose the clearest path L298N Motor Driver controls four BO motors for precise movement Robot makes intelligent decisions: reverse, turn left, or turn right based on environment ...

Laser Security System Using Arduino Laser Security System Using Arduino This project creates a laser-based security system that triggers an audible and visual alarm when the laser beam is interrupted. The system uses a laser module and LDR sensor to detect intrusions, with a buzzer and LED providing immediate feedback. The alarm features a distinctive "tuuuuu tuuuuu" pattern that lasts for 5 seconds when triggered. How the System Works Laser Module emits a continuous beam of light directed at the LDR sensor LDR (Light Dependent Resistor) detects the laser beam and maintains system in standby mode When the beam is interrupted: System triggers a 5-second alarm cycle Buzzer sounds with a distinctive "tuuuuu tuuuuu" pattern (700ms on, 300ms off) LED flashes in sync with the buzzer for visual indication After 5 seconds: S...
