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 shows how to build an infrared remote control (IR RC) converter that allows emulating an IR remote control (emulated IR RC) using a different one (physical IR RC). The basic principle is ...

[Fernando] sent in a tip about a pet project he’s been working on. It’s an interesting take on a 3D scanner. He used a stepper motor to rotate the object being scanned, and an Arduino for control, but ...

This project allows you to remotely control home appliances using an IR remote and an Arduino Nano. With this setup, you can manage up to 4 devices (such as lights, fans, etc.), and the system saves ...

I made this Arduino project that allows to turn ON and OFF LEDs using a cheap IR remote control as a preparation for the next big step: disassemble my girlfriend’s chinese LED lamp and replace its ...

(InfraRed remote control) A handheld, wireless device used to operate audio, video and other electronic equipment within a room using light signals in the infrared (IR) range. Infrared light requires ...
