Controlling an LED with Arduino Using an IR Sensor An Infrared (IR) sensor is a commonly used device for proximity detection and object sensing. When combined with an Arduino and an LED, it can create ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

Photoelectric sensors detect objects and surface changes using variations in optical properties. Each sensor includes a light emitter and a receiver, with most relying on infrared light. In optical ...

This project uses an Arduino UNO and IR sensors to create an intelligent traffic light system that adapts signal timing based on real-time vehicle presence.

Intrusion Detection Systems (IDS) strive to catch computer system intrusion & utilize by any garnering and analyzing data. Wireless IDSs garner all local wireless transmissions and generate alerts ...

Old infrared remote controls can be a great way to interface with your projects. One of [AnalysIR’s] latest blog posts goes over the simplest way to create an Arduino based IR receiver, making it ...

A light meter is a very useful device that finds applications in hospitals, schools, factories, parking lots, passageways, and many more to measure and maintain adequate lighting levels. It is also ...
