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 ...

Sometimes, it’s time to shut down the oscilloscope, and break out the cardboard and paints. If you’re wondering what for, well, here’s a reminder of an Instructable from [CrazyScience], that brings us ...

You would have probably read about the SONAR that’s used in ships. By taking the same concept into a small form factor we get a distance sensor. This sensor is available in multiple variants and I’ll ...

Arduino 20th anniversary projects at the University of Padua include a gesture-control car, solar IoT monitor, and BLE swim ...
