Intruder Alert!

In this task, you’ll create a simple intruder alert system using an ultrasonic sensor, LEDs, and a buzzer. When the ultrasonic sensor detects an object within a certain range, it will activate the alert by flashing three red LEDs and sounding the buzzer to indicate an intruder. This exercise reinforces sensor integration and expands your understanding of component interaction, as you’ll work with both visual and auditory signals for feedback. Through coding and wiring, you’ll gain experience in detecting proximity changes and triggering actions, a fundamental skill for designing responsive systems with Arduino.
