Design an Portable Ultrasonic Range Meter using Arduino

Portable Ultrasonic Range Meter

Under normal circumstances, the sound speed is 330m / s. SONAR or Sound Navigation and Ranging Route is a measure of distance communication that is commonly used on submarines. In this process, the high frequency sound is transmitted by the transmitter and the echo displayed from the object is captured by the receiver. As the speed of the sound wave is known, by measuring the travel time,
