hello mitro,
In this video, I built a smart distance indicator using an ultrasonic sensor, ESP32, and NeoPixel LEDs. The LEDs change color based on distance, giving a clear visual warning in real time. This project is perfect for beginners and useful for parking assistance, robotics, and obstacle detection projects. 🚀🔧
