Arduino Parking Sensor with LEDs 🚗

I created a parking sensor-like project using an Arduino Uno and an ultrasonic distance sensor. Based on the measured distance, different colored LEDs light up, and a buzzer provides an audible warning. This project is a fun and educational way to understand how parking sensors work! 🚗✨
