This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...

This project implements a rotating ultrasonic distance scanner using an Arduino, an HC-SR04 ultrasonic sensor, and an SG90 servo motor. Distance readings are transmitted over serial and visualized in ...

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 ...

PLCプログラムの学習や検証を始めたいけれど、できるだけ費用を抑えたい。そのような方には、OpenPLCとArduinoの組み合わせが最適です。 はじめに OpenPLCは、オープンソースで全ての機能を無償で使用することができ（IEC-61131-3に準拠しています）、 作成し ...

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 ...
