This project aims to learn how to interface and use the HC-SR04 ultrasonic module with the Arduino UNO board.
The HC-SR04 Ultrasonic Module is a popular ultrasonic distance sensor used in a variety of electronic applications. It is widely used to measure the distance between an object and the sensor, making it useful in robotics, automation, and home automation projects. The HC-SR04 Ultrasonic Module uses high-frequency sound waves to measure the distance between the sensor and an object. The module consists of an ultrasonic transmitter and an ultrasonic receiver. When the transmitter emits high-frequency sound waves, they travel through the air until they encounter an object. When the sound waves hit an object, they bounce back and are received by the receiver. The HC-SR04 Ultrasonic Module is easy to use with an Arduino board or other microcontrollers. It is typically powered by a 5-volt supply and uses digital pins to control the emission of sound waves and retrieve the measured distance data.
