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 ...

This Arduino project controls a servo motor based on distance measured by an HC-SR04 ultrasonic sensor, adjusting to four angles for different proximity ranges. It updates only when significant ...

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 ...
