I will use this sensor (or its latest version) in a more complex project in the next part of this post. Stay tuned for that do it yourself project. Below is the Arduino Sketch used to test the ...

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 ...

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.

An ultrasonic sensor is positioned outside the box to detect the presence of a hand within a four-inch range. Upon sensing an obstacle, ... the Arduino code is equally basic, too.

Inside the 3D printed enclosure is an Arduino Pro Mini, a HC-SR04 ultrasonic sensor, and a 1602 serial LCD. Once the gadget has been mounted in the proper position and activated, ...

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 ...

To supply targeting data for the launcher, an Arduino Uno uses an ultrasonic sensor pair mounted atop a servo. ... Looking through the code, looks like serial between Arduino and Pi.

The official Arduino Blog has this week featured a new project which demonstrates ultrasonic Arduino to Arduino communication by Brazilian maker Eduardo Zola. Showing that you can communicate ...

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 ...
