Distance Monitoring System

Arduino-based system that measures distance using an ultrasonic sensor and displays results on an LCD.

Features

• Real-time distance measurement
• LED status indicators (SAFE / MID / CLOSE)
• LCD display output
• Smoothed sensor readings

Components

• Arduino Uno
• HC-SR04 Ultrasonic Sensor
• 16x2 I2C LCD
• LEDs + resistors

How it works

The system continuously measures distance and:

• Displays the value on the LCD
• Uses LEDs to indicate proximity levels
