What if your Arduino could notice someone getting close without touching anything at all? No buttons, no pressure sensors, no physical contact - just light. That idea might sound a little bit like ...

As you might have noticed, the 38-KHz pulse generator is built around the evergreen timer chip NE555P (IC1). Here, the RC components (R5-C3-P1) set the astable frequency to drive the infrared light ...

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 ...

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 ...

A simple IR (Infrared) Obstacle Detection Sensor Module designed using discrete electronic components. The circuit uses an IR LED to emit infrared light and a photodiode to detect reflected IR rays.

This project is an Arduino-based laser tag system designed for customizable, low-cost gameplay. It combines infrared (IR) communication, sensors, and visual feedback to simulate a real laser tag ...
