To build a system where an LED blinks whenever the IR sensor detects an object within its proximity range. This can be used in various applications, such as a simple object detection system or a ...

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 ...

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 ...

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 ...

A large installed base of powered speakers from a defunct manufacturer and a dwindling supply of working remote controls. Sounds like nightmare fuel for an AV professional – unless you take matters ...

Here is a 3D light show that will astound you with its combinations. Inexpensive and easy to make thanks to an Arduino controller, the design enables you to play with the existing effects and, most ...
