This project combines a joystick, servo motor, ultrasonic sensor, two LEDs, and a buzzer to create an interactive object detection system. The joystick is used to rotate the servo motor left and right ...

Walking safely and confidently can be a challenging task for visually impaired individuals, but with the help of technology, we can make it easier for them. This DIY Blind Stick is an innovative yet ...

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 ...

The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...

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 ...

If you’re going outside (only for essential grocery runs, we hope) and you’re having trouble measuring the whole six feet apart from other people deal by eye, then [Guido Bonelli] has a solution for ...
