This project is based on an HC-SR04 ultrasonic sensor with Arduino to measure distance between the sensor and an object. The sensor sends ultrasonic waves and receives the reflected signal. The time ...

The ultrasonic distance sensor (HC-SR04) is a widely used electronic component for non-contact distance measurement. It operates on the principle of echo-ranging, where it emits an ultrasonic pulse ...

[Klaus] wanted some sort of aid for parking his car, and after running across a $4 ultrasonic sensor, decided to build his own speaking distance sensor (.de, Google Translation). Inside [Klaus]’ ...

This post is a review of the popular waterproof ultrasonic sensor JSN-SR04T. I hope this will serve as a backdrop for some interesting ultrasonic distance sensor experiments and projects. A number of ...

In the real world, missile systems use advanced radars, infrared sensors, and other hardware to track and prosecute their targets. [Raspduino Uno] on YouTube has instead used ultrasound for targeting ...

The Turtle Bot is one of the classics for Arduino tinkering. The YouTuber UncleStem has built it seven times larger – and it works.
