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 ...

This project implements an obstacle-avoiding robot using an ultrasonic sensor for distance measurement and motor driver control. The robot moves forward until it detects an obstacle within 15 cm, at ...

This project involves building an Arduino-based auto-driving car that utilizes ultrasonic sensors to detect obstacles and make decisions on movement. The car can be started using a push button, and it ...

Our IoT-Based Smart Bin project features a custom-built IoT system and Firebase database, using the Arduino Uno R4 WiFi. Dual ultrasonic sensors handle motion and fill-level monitoring, with an ...

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 ...

The HC-SR04 ultrasonic range sensor is a pretty cool pre-wired module that you actually enjoy using when you start playing with electronics, microcontrollers, and robotics. As you might have noticed, ...
