A small PlatformIO/Arduino project that measures distance using an ultrasonic sensor (HC-SR04 or similar) and prints the measured distance over the serial port. This README explains how to open the ...

Simple Arduino sketch that measures distance using an HC-SR04 ultrasonic sensor and prints the value to the serial monitor at 9600 baud.

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 ...

The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...

The value of a mirror is in its clarity. If the reflection is cast by [danicakostic17]’s Uncooperative Mirror though, you’ll find anything but. It’s described as a useless machine, because it appears ...

Smart Blind Stick using Arduino 👨🦯🔔 I developed a Smart Blind Stick using Arduino and an Ultrasonic Sensor to help visually impaired people detect obstacles in front of them. 🔧 Components used: ...
