Arduino Tutorials: How to Use the HC-SR04 Ultrasonic Sensor for Distance Measurement

In this Arduino Tutorial, you’ll learn how the HC-SR04 Ultrasonic Distance Sensor works and how to understand its 4-pin configuration. This video covers the internal working principle of the sensor, how ultrasonic waves are used to measure distance, and what each pin (VCC, Trig, Echo, GND) does. 📌 Topics Covered: • HC-SR04 working principle explained • Role of each pin: VCC, Trigger, Echo, GND • Timing and signal flow 💡 This is a theoretical guide—no Arduino wiring or code in this video. Perfect for beginners who want to understand the sensor before building a project. 📺 More Tutorials: 👉 https://www.youtube.com/playlist?list=PLUYMB54_TFeSJ3JOCQCnj9rQ7qDmOKBDJ 👍 Subscribe for more hardware-focused tutorials. 💬 Have questions?
