Description
🎓 Smart Distance Measurement Project with OLED Display is Here!
We’ve officially launched Project Kits & Fully Assembled Ready Projects 🔧 for students, makers, and innovators — now you can buy complete working projects directly from Dream RC! 💥
⚙️ Project Concept & Working Principle:
The Smart Distance Alert System Measure distance accurately in real time using an Ultrasonic Sensor + OLED Display + ESP32 combo.
It shows live distance readings on the OLED screen, and the LED indicator changes based on how close an object is! 🟢🟡🔴
(You can even set your own distance limit to trigger the LED alert — fully customizable! 😎)
- 📺 The measured value is displayed on the 0.96” OLED screen, and based on the distance range —
Depending on the detected distance, LEDs and buzzer indicate proximity:
🟢 Green LED: Distance > 50 cm (safe distance)
🟡 Yellow LED: Distance between 25–50 cm (warning zone)
🔴 Red LED: Distance < 25 cm (danger zone) + buzzer alert
This gives a visual + sound alert system, perfect for learning sensor-based logic and basic automation! ⚡
This project gives beginners a clear understanding of how sensors, displays, and Arduino work together.
💬 Notes:
📏 Effective measuring range: 2 cm to 400 cm (4 meters)
⚙️ You can easily change the LED distance thresholds in the Arduino code to your desired range — perfect for experiments and customization!
🔌 9V battery or DC adapter compatible for flexible powering.
