Car Parking Sensor Using ATmega32, Ultrasonic Sensor, LCD Display, LEDs, and Buzzer.

تصميم نظام بسيط لمساعدة السائقين على كشف العقبات وتجنب الاصطدام أثناء الركن. يستخدم النظام حساسًا بالموجات فوق الصوتية لقياس المسافة، وشاشة LCD لعرض النتائج، مع تنبيهات بصرية وصوتية عبر LEDs وجهاز إنذار (Buzzer) بناءً على قرب العائق.

Overview:

This project uses an ATmega32 microcontroller to process distance data

from an ultrasonic sensor and display the results on an LCD. The system

includes three LEDs (Red, Green, and Blue) and a buzzer for indicating the

proximity of an obstacle. The LEDs light up progressively and the buzzer

activates as the obstacle gets closer, helping drivers park safely.

Features:

• Ultrasonic Distance Measurement: The ultrasonic sensor measures the

distance between the car and any nearby object.

• LCD Display: Displays the distance measured by the ultrasonic sensor in

centimeters. Also displays "Stop" if the distance is less than 5 cm.

• LED Indicators: Three LEDs (Red, Green, and Blue) light up according to the

proximity of the object.

• Buzzer Alert: The buzzer sounds when the object is too close (<= 5 cm).

• Dynamic LED Behavior: LEDs turn ON/OFF based on the following distance

ranges.
