Learn how to use ultrasonic sensor HC-SR04 with Arduino, how ultrasonic sensor works, how to connect ultrasonic sensor to Arduino, how to code for ultrasonic sensor, how to program Arduino step by step.
In this tutorial you will learn how the HC-SR04 ultrasonic distance sensor with an Arduino. Wiring diagrams and code included!
In this project, we use HC-SR04 Ultrasonic Distance Sensor with Arduino for displaying the measured distance on an LCD screen. The HC-SR04 sensor operates on the principle of sonar, emitting an ultrasonic wave at a specific frequency that reflects off an object and returns to the sensor.
