This work presents the development of an Ultrasonic Range Finder utilizing readily available components, including an Arduino microcontroller, an HC-SR04 Ultrasonic Sensor, a 16x2 LCD Display, and an I2C LCD Module. This system measures distances accurately by sending out ultrasonic waves and figuring out how long it takes for them to come back. The Arduino processes this data and displays the distance on the LCD screen in real time. The hardware setup involves wiring the HC-SR04 sensor to the Arduino to facilitate communication and power supply. Additionally, the 16x2 LCD Display is connected to an I2C module, simplifying the wiring process and enabling easy communication between the Arduino and the LCD. The Arduino code implements the functionality by periodically triggering the ultrasonic sensor, measuring the time it takes for the ultrasonic waves to return, and converting this time into distance measurements in centimeters. These measurements are then displayed on the 16x2 LCD in a user-friendly format. This work serves as a practical example of sensor integration, data processing, and real-time display on an LCD screen. It can be a valuable educational resource for those interested in Arduino-based projects and the principles of ultrasonic distance measurement.
