🔹 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 project is based on Arduino UNO and an ultrasonic sensor. It is designed to measure distance and trigger a buzzer if the measured distance is below a certain threshold.

If you've always wanted to try to build an Arduino project, this may be a great way to start. Matt Williamson built a tiny, Arduino-based motion sensor that will SMS you when something moves by ...

Considering the existing solutions for distance measurement for robots and quadcopters, this sensor will certainly make for some very awesome projects.

He suspected EMF interference so as a quick first step he decided to throw together an EMF detector using an Arduino. It uses a bank of LEDs as an indicator bar to reflect the EMF picked up by the ...
