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 ...

By integrating advanced sensors and optimizing the power management of the ESP32, I've created a DIY smart lock that is both ...

A very cool (also warm!) property of the base-emitter junction of (most) small signal BJTs is the ΔVbe temperature-sensing ...

If you were to point to a single device responsible for much of Hackaday’s early success, it might be the Arduino Uno. The ...

The last week of the release continued the same “lots of small fixes” trend, but it all really does seem pretty benign, so I’ve tagged the final 7.0 and pushed it out. I suspect it’s a lot of AI tool ...

Abstract: Drunk driving remains a significant issue worldwide, with thousands of lives lost every year due to accidents caused by individuals operating vehicles under the influence of alcohol. The ...

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, ...
