The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...

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 ...

Use an infrared remote to control your computer, when i say control, i mean basic functionnalities like left and right click, mouse movements, etc.. To do so, i used an arduino uno and an infrared ...

Automating household or office systems can be achieved using an Arduino Nano, a passive infrared (PIR) motion sensor, and a relay. The primary aim is to create a control system that activates or ...
