[mircemk] shows how to create a simple non-contact proximity sensor using little more than an Arduino Nano board, and a convenient software library intended to measure the value of capacitors. The ...

An embedded proximity monitoring system built using an Arduino Uno and ESP32. The system combines ultrasonic distance sensing, servo-based scanning, RGB LED and buzzer alerts, manual/automatic ...

It seems like engineering 101, but do you actually remember the specific differences between inductive proximity, inductive displacement, and eddy-current sensors? I asked a few friends and everyone ...

A simple Arduino Uno project to measure distance using an HC-SR04 ultrasonic sensor and indicate proximity zones using 3 LEDs. About : In this project, an HC-SR04 ultrasonic sensor is used to detect ...
