Project Details
How It Works
How It WorksThe project works by using a PIR motion sensor to detect changes in infrared radiation caused by human movement. The sensor sends a digital HIGH signal to Arduino's D2 pin when motion is detected. Arduino reads this input and activates the buzzer on D8 and LED on D9 to create an audible and visual alarm. The system continuously monitors the sensor and updates the alarm state based on motion detection, with serial output for debugging.
Prerequisites
Basic understanding of Arduino programming and electronics. Familiarity with digital input/output pins and simple circuit connections. Knowledge of how to install Arduino IDE and upload code to Arduino board.
