🔹 Project Details: Smart LED Distance Indicator using Ultrasonic Sensor and Arduino 📌 Introduction This project is a real-time distance indicator using an HC-SR04 ultrasonic sensor and LEDs to ...

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 ...

The most commonly used distance measuring sensors are: Ultrasonic Distance Sensors Laser Distance Sensors Infrared Distance Sensors Time of Flight (ToF) Sensors Time-of-Flight (ToF) sensor is a very ...

One major problem of ultrasonic distance measurement is the strongly object dependent detection range: objects providing strong echoes (e.g. well aligned planes) can be detected in a much wider ...

Efforts have been made to measure the distance traveled by humans in motion, in ways that are compact and accurate, for a long time. There are several ways to measure the distance moved by walking or ...
