Arduino Distance Measurement System (Ultrasonic + OLED)

I built an Arduino-based Distance Measurement System using an Ultrasonic Sensor (HC-SR04) and a 128×64 OLED display. The project measures the distance between the sensor and any object in front of it, then displays the value in real-time on the screen. It is accurate, simple to use, and ideal for beginners, students, and robotics applications.

Features:

Real-time distance measurement

Clear OLED display

Uses the HC-SR04 ultrasonic sensor

Easy wiring and clean Arduino code

Can be expanded for robotics, obstacle detection, or smart systems

What I Provide:

Full Arduino code

Circuit diagram + wiring guide

Setup instructions
