The code includes two Arduino libraries: one for the servo and another for the ultrasonic sensors. The main code is a simple 14-line piece with a simple if-else statement you can readily modify.

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 ...

This ultrasonic radar project is from [mircemk] who uses a small ultrasonic distance sensor attached to a rotating platform. A motor rotates it around a 180-degree field-of-view and an Arduino ...

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.

Patrick explains a little more about the new Arduino ultrasonic experiment kit and its functionality : This bad boy can be re-programmed with your own code, and the included code samples can be ...

An Arduino polls the ultrasonic sensors and provides feedback via the boxes. This completely frees up the user's hands for other tasks. Advertisement. While the prototype has a ways to go, such as ...
