Interfacing Ultrasonic Sensor and LCD Display With Arduino Uno

In this project, we will employ ultrasonic sensor with Arduino to display the distance of an obstacle on the LCD.

The HC-SR04 ultrasonic sensor employs sonar to determine the distance to an object or obstacle like bats do. It offers excellent range detection with high accuracy and stable readings with detection ranging from 2cm to 400 cm and accuracy of up to 3mm. Its operation is not affected by sunlight but acoustically soft materials like cloth can be difficult to detect. It comes with a complete package of ultrasonic transmitter and receiver module mounted on it.
