IR (Infrared) communication is simple, low-cost, and widely used wireless communication technology. IR light is somewhat similar to the visible light, except that the wavelength is slightly longer.

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 ...

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, ...

This project enables a computer to be powered on using an infrared (IR) remote control. An Arduino Uno receives the IR signal and activates a relay module that simulates pressing the PC’s physical ...

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 ...

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 ...
