DIY - Ultrasonic Distance Measuring Kit - Arduino Nano, OLED, Ultrasonic Sensor

Overview

Measure distance in real time using ultrasonic sound waves, with live readings shown on an OLED display — a compact, beginner-friendly sensor project.

How It Works

1. The HC-SR04 sensor sends an ultrasonic pulse and measures the time for its echo to return.
2. The Arduino Nano converts this time into a distance measurement.
3. The result updates live on the OLED display.

FAQ

Do I need coding experience? No prior experience is required — this kit is built around one specific project, and the full code is freely available. See the build guide above.

What tools do I need beyond what's included? A computer with the free Arduino IDE (or ESP32/ESP8266 board support, where applicable) installed to upload the code. No soldering is required for this build.

Can I reuse the parts afterward? Yes — every component in this kit is a standard, reusable part you can use in future projects, not a single-use kit.
