This project uses an HC-SR04 ultrasonic sensor to measure how close an object is. A buzzer and LED react depending on the distance, similar to a car parking sensor. < 10 cm → buzzer and LED stay on.

This project demonstrates a line-following robot built using an Arduino Uno, IR sensors, DC motors, and an ultrasonic sensor. The robot can detect and follow a black line on a white surface and avoid ...

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 ...

In the real world, missile systems use advanced radars, infrared sensors, and other hardware to track and prosecute their targets. [Raspduino Uno] on YouTube has instead used ultrasound for targeting ...

Abstract: The design of a “third eye for the blind,” which employs ultrasonic waves to detect surrounding obstructions and notify users with a buzzer sound or vibration, is made feasible by the ...

Today, we are building a simple Arduino-based project: a light-following robot. This project is perfect for beginners, and we'll use LDR sensor modules to detect light and an MX1508 motor driver ...

We may receive a commission on purchases made from links. If you have an interest in electronics and have been hanging around DIY tech forums for a while now, chances are you already know what an ...

Gas leaks can pose serious safety risks, especially in homes, kitchens, and small commercial spaces. In this project, you'll learn how to build a simple and budget-friendly gas leakage detector using ...
