I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

Arduino-Defence-System This project combines the power of Arduino, radar technology, and lasers to create an innovative system capable of detecting and tracking objects. The radar, mounted on a servo ...

Project Overview: This project involves creating a functional radar system using an ultrasonic sensor, Arduino Uno, and a breadboard. The radar is capable of detecting objects within a specified range ...

Makers, Arduino enthusiasts and students looking to learn more about ultrasonic sensors, may be interested in this DIY Arduino radar created by Mr Innovative. Capable of detecting objects placed in ...

[Dustin Andrews] built this add-on board which works as a proximity sensor. He wanted a standalone sensor for his Arduino projects which would use a single pin as a trigger. This lets him alert the ...

Abstract: This research aims to develop a RADAR system using an ultrasonic sensor (HC-SR04), servo motor (SG90), and Arduino UNO. This RADAR system can detect objects in the vicinity and display ...
