Ultrasonic sensor (HC-SR04) is commonly used to find the distance of an object from one particular point. It has been fairly easy to do this with the Arduino ... Now we can use the above mentioned ...

It is very easy to write a code on the Arduino board and integrate an ultrasonic sensor to carry out this task. But in this article, we are going to adopt a different approach. We are going to use two ...

If you need to measure a distance, it is tempting to reach for the ubiquitous ultrasonic module like an HC-SR04. These work ... than two ping-pong balls. It needs 5 V but communicates using ...

Ultrasonic sensors are an inexpensive way to make robots see. The sensors send out sound waves to detect objects. While both glass and most plastics are solid objects that impede sound, acoustically ...
