Arduino code for detecting basic hand gestures using HC-SR04 ultrasonic distance sensor array. This code utilizes three HC-SR04 ultrasonic distance sensor modules placed linearly with a fixed distance ...

🔹 Project Details: Smart LED Distance Indicator using Ultrasonic Sensor and Arduino 📌 Introduction This project is a real-time distance indicator using an HC-SR04 ultrasonic sensor and LEDs to ...

Infrared certainly has its uses, but if you’re trying to locate objects, ultrasonic detection is far superior. It’s contact-less, undetectable to the human ear, and it isn’t affected by smoke, dust, ...

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 ...

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 ...

In this paper, we use the Arduino platform together with sensors as accelerometer, gyroscope and ultrasound, to measure vibrations in mechanical systems. The main objective is to assemble a signals ...

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 ...
