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 ...

This post is a review of the popular waterproof ultrasonic sensor JSN-SR04T. I hope this will serve as a backdrop for some interesting ultrasonic distance sensor experiments and projects. A number of ...

A low-cost (~$100), do-it-yourself (DIY) ultrasonic water level sensor/datalogger has been designed, constructed, and tested for use in education, citizen/community science, and research settings. The ...

Honestly, if it weren’t for the ultrasonic distance sensor protruding from the spherical body, you might think that the entire robot was just a little Wiffle ball.

So if you think your Arduino programming could benefit our someone else’s, visit the Kickstarter website now to make a pledge and help the DuinoKit Essential Project become a reality.

John Boxall, author of the new book Arduino Workshop, shares a few of the projects from his book on how to get started with the microcontroller. (Click the links to see PDFs of the complete ...
