[Klaus] wanted some sort of aid for parking his car, and after running across a $4 ultrasonic sensor, decided to build his own speaking distance sensor (.de, Google Translation). Inside [Klaus]’ ...

Working with multiple sensors on an Arduino can unlock richer, more interactive projects. By integrating motion, light, distance, and environmental readings, you can create systems that respond ...

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 ...

Arduino sensor projects blend coding with tangible results, making learning interactive, practical, and fun. From simple LED triggers to multi-sensor systems, these builds teach real-world electronics ...

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 ...
