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 ...

but for simplicity and because of all the sensor modules available for it, the Arduino was the chosen one. The robot's eyes and ears are provided by an ultrasonic sensor and an infrared sensor ...

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 ...
