Shifting to the new waterproof ultrasonic sensor is not a big deal, since it’s pretty easy to modify some example codes to use it. The quick road test, oh it’s a simple approach to display the ...

With a standard old HC-SR04 ultrasonic sensor, an audio module and a servo ... sound like for anyone who has a bunch of these little Arduino-compatible modules lying around and has probably ...

Patrick explains a little more about the new Arduino ultrasonic experiment ... you can interface the HC-SR04 ultrasonic ping sensor with a servo motor and the main board (Only some reward tiers ...

An ultrasonic sensor is positioned outside the box to detect the presence of a hand within a four-inch range. Upon sensing an obstacle, it then sends a signal to the Arduino UNO, which ...

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 ...

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 ...
