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 ...
Producing items onto a screen simply by touching the air is a marvelous thing. One way to accomplish this involves four HC-SR04 ultrasonic sensor units that transmit data through an Arduino into a ...
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 ...
A LiDAR-inspired 3D spatial mapping system built from scratch using an ultrasonic sensor, custom pan-tilt mechanism, and Python-based point cloud visualization — at a fraction of LiDAR cost. 3D ...
