Ultrasonic Distance Measurement with Arduino This project demonstrates how to use an HC-SR04 ultrasonic sensor with an Arduino to measure the distance to an object. The distance is calculated based on ...

This project utilizes an Arduino microcontroller along with an ultrasonic distance sensor to measure distances and provide warnings when objects are detected within certain ranges. The distance ...

Buy arduino, buy sound shield, buy distance sensor shield, plug into each other, burn example code, stuff components inside box. Not only is this not a hack but he might as well have just bought a ...

The spacing and number of sensors depend on the shape of the vacuum and the field of view of the ultrasonic sensor. As the vacuum – or other robotic devices – roams around a smart home or building, ...

Smraza 5pcs Ultrasonic Module HC-SR04 Distance Sensor with 2pcs Mounting Bracket for Arduino R3 MEGA Mega2560 Duemilanove Nano Robot XBee ZigBee ...

In this paper, we consider to use a low-cost ultrasonic distance sensor attached on a bicycle for monitoring the road surface conditions in the front area. We design and implement a road surface ...

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.
