Here is a quick tutorial on how to measure distance using ultrasonic sensor and arduino.
It sends an ultrasonic wave of a certain frequency that comes back after hitting the object and calculates the time traveled by it.
And then perform calculations and displayed result on 16x2 lcd by using appropriate functions.
1 arduino uno r3.
Working of ultrasonic sensor.
The module sends 40 khz signals automatically and then detects whether the pulse is received or not through echo.
In this tutorial we ll understand the working of ultrasonic sensor understand the arduino program for distance measurement using ultrasonic sensor hc sr04.
The high level signal is sent to 10 microseconds using trigger.
Distance measurement using ultrasonic sensor.
Find more about the working of distance measurement project in this tutorial.
