Ultrasonic Distance Measurement with Arduino This project demonstrates how to use an HC-SR04 ultrasonic sensor with an Arduino to measure the distance to an object. The distance is calculated based on ...

•An Ultrasonic sensor and a 16X2 LCD display were interfaced using Arduino Uno R3 Microcontroller to measure the distance from the sensor to an obstacle placed in front of it.•The LiquidCrystal.h ...

One sensor will be made a receiver and the other will be made a transmitter. By doing so, we will be able to measure the distance between them just by locating the position of the transmitter by using ...
