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 ...

This project is an advanced Arduino-based control system that integrates a sound sensor, a light sensor (LDR), an IR remote, and a buzzer to respond intelligently to environmental conditions. The ...

Have you ever noticed how shopping malls, parking lots, or event venues seem to track the number of people or cars present inside? You might think they use an AI camera to count them, but in reality, ...

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 ...

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 ...

We’ve featured loads of IR Arduino projects and they are all exciting and unique. The projects spring from a specific need or problem where a custom infrared remote control is the solution. [Rick’s] ...
