Arduino Tutorial for Beginners: 06 -Distance measuring using Ultrasonic Sensor
Project Title:
Ultrasonic Distance Measurement with LCD Display using Arduino Uno
Project Description:
In this project, we interface an Ultrasonic Sensor (HC-SR04) with an Arduino Uno and a 16x2 LCD display to measure and show the distance between the sensor and an object placed in front of it. This is done by using ultrasonic sound waves to detect the distance and then displaying the measured value in centimeters on the LCD screen.
The ultrasonic sensor works by emitting high-frequency sound waves through its trigger (Trig) pin and then listening for the echo via its echo (Echo) pin. By calculating the time between the trigger and echo signals, the Arduino can calculate the distance to the object
