Interface an Ultrasonic Sensor Arduino Project Hub

The ultrasonic sensor from Parallax consists of 3 pins: GND, 5V, and SIG. The SIG pin is used as both an input and an output. It is an input when the Uno sends a HIGH pulse to trigger the sensor to take a measurement, and it is an output when the sensor sends a HIGH pulse where the length of the pulse is dependent on the time it takes for the transmitted sound wave to return. It can measure ...
