This project involves using an Arduino to measure distances using an ultrasonic sensor and controlling a buzzer and LED based on the measured distance. The provided Arduino code performs the following ...

In this project I did a Christmas jumper with rgb LEDs, this can also be a creative clothing project or whatever you want, it uses rgb LEDs that are controlled by an Arduino-based microcontroller that ...

As AI coding tools generate billions of lines of code each month, a new bottleneck is emerging: ensuring that software works as intended. Qodo, a startup building AI agents for code review, testing, ...

There are plenty of drones (and other gadgets) you can buy online that use proprietary control protocols. Of course, reverse-engineering one of these protocols is a hacker community classic. Today, ...

In this video I'm walking you through the steps I took to make a standalone version of my pellet level monitoring sensor that is not directly connected to Home Assistant but it functions separately .

Works with the HC-SR04 ultrasonic sensor in the 3 Pin Mode/4 Pin Mode, the Ping))) ultrasonic sensor in the 3 Pin Mode and the DHT temperature/humidity sensors for getting precise distance values. !

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, ...

Abstract: Ultrasonic index modulation can effectively improve the spectral efficiency and energy efficiency of intra-body communication systems. This letter proposes a codeword-based auto-correlation ...
