This library is using a hardware interrupt to monitor Echo pin state change instead of using pulseIn function which pauses code execution. The library enables the user to use this sensor with only 2-3 ...

In this project I did a Christmas jumper with rgb LEDs, this can also be a creative clothing project or whatever you want, it ...

Home automation with high usefulness and low annoyance tends to rely on reliable person sensing, and [francescopace]’s ESPectre shows one way to do that cheaply and easily by leveraging ...

A common sight in ‘smart homes’, door sensors allow you to detect whether a door is closed or open, enabling the triggering ...

Abstract: Radar technology has been a cornerstone of numerous applications, from aviation to meteorology, offering invaluable capabilities for object detection and tracking. Traditional radar systems, ...

Arduino test code is run to see if the sensors are working properly, with built-in LED flashing when the sensor is triggered, and turning off when the sensor is released. The testing of the keys ...

This project implements a real-time closed-loop motor control system where motor speed is dynamically regulated based on obstacle distance. An ultrasonic sensor provides the reference input, an ...

Abstract: The stress field of steel members in service is unevenly distributed under complicated loads. The existing single-path ultrasonic (SPU) sensors can only measure stress in a single ...
