This is an Arduino project using an HC-SR04 Ultrasonic Sensor and LEDs to measure the distance of objects, similar to a scale. When an object comes close to the HC-SR04 ultrasonic sensor, it indicates ...

In this project, I developed an innovative hardware solution utilizing an Arduino Uno board paired with an ultrasonic sensor to create a real-time object detection system. The primary objective was to ...

Fans of the bouncing lamp from the Pixar corporate logo will enjoy [Daniel]’s latest project. It’s a motion controlled desk lamp that uses ultrasonic sensors to control its physical position. The core ...

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 ...

Have you ever wondered how speed guns measure the speed of moving vehicles or how an athlete's sprint speed is recorded? Normally these speed sensors work with radar or laser technology to bounce back ...

Gas leaks can pose serious safety risks, especially in homes, kitchens, and small commercial spaces. In this project, you'll learn how to build a simple and budget-friendly gas leakage detector using ...

This is a simple arduino project for a soil moisture sensor that will light up a LED at a certain moisture level. It uses Arduino Duemilanove microcontroller board. Two wires placed in the soil pot ...
