I have created a model of an Ultrasonic Distance Sensor with a button to activate the sensor portion along with an LED to light up once a certain distance has been reached. Code will be written in ...

Intelligent Headlight Control System: an Arduino prototype with an LDR for ambient light sensing and an HC‑SR04 ultrasonic sensor for vehicle detection. It uses PWM to adjust LED brightness, reducing ...

Abstract: A simple robotics project simulated in Tinkercad based on Arduino Uno. It uses ultrasonic sensors for obstacle detection and can do basic movements using DC motors. The primary objective of ...

If you need some sort of distance sensor for your robot, drone, or other project, you have two options: a cheap ultrasonic sensor with limited range, or an expensive laser-based system that’s top of ...
