In this project, I developed an innovative hardware solution utilizing an Arduino Uno board paired with an ultrasonic sensor to create a real-time object detection system. The primary objective was to ...

Let me introduce another simple microcontroller-based do-it-yourself circuit that detects motion and excites a light source in a flash. The “snooper” here is an ordinary passive infrared (PIR) motion ...

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 ...

Explore how the integration of a standard ultrasonic sensor, a vibration motor, and one or two microcontrollers resulted in a functional enhancement for a mobility aid. The developed ultrasonic ...

This project is an IoT-based real-time object detection and alert system designed to monitor restricted areas. It uses an ultrasonic sensor to detect objects within a specified distance and triggers ...
