In this detailed video tutorial, we’ll guide you through the process of designing and building a simple yet effective distance measurement device. This project utilizes an Arduino Uno, an HC-SR04 ultrasonic sensor, a 1602 LCD display, a potentiometer, jumper wires, and a breadboard. It’s an excellent starting point for beginners who are new to electronics and programming, as well as those curious about sensor-based projects.

What Does This Project Do?
The core of this device is the HC-SR04 ultrasonic sensor, which works by emitting ultrasonic sound waves and detecting their echoes after bouncing off an object. The time it takes for the echo to return is used to calculate the distance to the object. This distance is then displayed in real time on the 1602 LCD, providing a clear and convenient readout.
To make the LCD output legible under different lighting conditions, we use a potentiometer. By turning the potentiometer knob, you can easily adjust the LCD’s contrast, ensuring the characters remain visible no matter the viewing angle or ambient lighting.
