In this video, Dejan Nedelkovski will show you a cool radar project using an Arduino board. The project is very simple using only an ultrasonic sensor for detecting an object, a small servo motor used ...

Ultrasonic rangfinders are a cheap and easy way to gather obstacle avoidance data. When added to a servo motor they form something of a scanning radar for near-proximity objects. In this ...

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 ...
