In this project I will introduce you to the HC-SR04 Ultrasonic sensor. It works by sending sound waves from the transmitter, which then bounce off of an object and then return to the receiver. You can ...

This project uses an HC-SR04 ultrasonic sensor and Arduino UNO to measure the distance of objects in both centimeters and inches. The measured data is displayed on an I2C LCD. The project was ...

Instead, it relies on an ultrasonic distance sensor to detect a hand (or foot) waved in front of the door. An Arduino Leonardo runs the show, sounding a buzzer when the ultrasonic sensor is triggered.

Arduino Uno – Powered Parking Guidance System with Ultrasonic Sensors" is a smart and innovative solution for simplifying the parking process in crowded urban environments. This paper leverages the ...

Everything always looks good on paper (and in its seller’s description), so I plugged my module into an Arduino Prototyping Shield for a quick/lazy evaluation using an Arduino Uno. If you have played ...

To supply targeting data for the launcher, an Arduino Uno uses an ultrasonic sensor pair mounted atop a servo. As the servo rotates, the returns from the ultrasonic sensor are plotted on a screen ...
