This project will show you how to use an ultrasonic sensor with an Arduino. What is an ultrasonic sensor? An ultrasonic sensor is a module which uses ultrasound (you didn't expect that, did you?). It allows to detect a presence or to measure a distance via ultrasounds. He sends an ultrasound pulse via his trig terminals and receives them via his echo terminals. The ultrasonic sensor sends 8. Arduino - Ultrasonic Sensor. Arduino's pins can generate a 10-microsecond pulse and measure the pulse duration. Therefore, we can get the distance from the ultrasonic sensor by using two Arduino's pins: One pin is connected to TRIG PIN to generate 10µs pulse to TRIG pin of the sensor; Another pin is connected to ECHO PIN measure pulse from the sensor ; Wiring Diagram.
