This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module ... cm from the HC-SR04 module), and an ear-splitting beep from the piezo-buzzer otherwise.

Watch the demonstration video below to learn more about the ultrasonic race timer and ... tools and we will use popular components like Arduino, buzzer, buttons, and one that’s not so popular ...

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 ...

This one is an unusual smart home project, potentially - how to monitor a fish tank’s health with an AI-enabled ultrasonic sensor system. The detailed project is highlighted on Hackser.io and features ...
