This DIY solar tracker project mimics this behavior using three simple main components: An Arduino UNO board, a servo motor (with ... closing the lid, an ultrasonic sensor in front of the bin ...

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 ...

but we do know her Arduino does. Her build uses the ubiquitous HC-SR04 SONAR sensor and a servo. This is a great use for a servo since a standard servo motor without modifications only moves ...

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 ...
