About This project is a real-time distance indicator using an HC-SR04 ultrasonic sensor and LEDs to visually represent object proximity. It is designed to provide intuitive feedback for applications ...

An Arduino project using a servo motor and ultrasonic sensor to measure distances and scan the environment. The servo rotates, allowing the ultrasonic sensor to capture distance data at various angles ...

This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...

This is not the first Time of Flight distance sensor on the market; earlier this week we saw a project use a sensor called the TeraRanger One. This sensor costs €150.00.

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 ...
