This schematic was designed using EasyEDA and shows the complete connection setup of the ultrasonic sensor (HC-SR04) with the Arduino UNO and two LEDs. It includes pin mappings, power rails, and ...

📝 Descripción del Proyecto Este proyecto utiliza un sensor ultrasónico HC-SR04 y dos LEDs (rojo y verde) para crear un sistema de medición de proximidad con Arduino. El sensor detecta la distancia de ...

The HC-SR04 sonar modules are available for a mere pittance and, with some coaxing, can do a pretty decent job of helping your robot measure the distance to the nearest wall. But when sellers on eBay ...

Some of the best hacks are the ones which seem perfectly obvious in hindsight; a solution to the problem that’s so elegant, you wonder how it never occurred to you before. Of course we also love the ...

Abstract: The automation of height-increasing bridges during floating events is a crucial engineering challenge in areas prone to flooding or water surges. It proposes a solution to adjust the bridge ...
