The part list consists of one Arduino, two resistors, and one IR emitter. That’s right, an emitter. When an LED (IR or otherwise) is reverse biased it can act as a light sensor.

The hardware will capture an IR code and retransmit it on demand. The schematic isn’t particularly complex. The IR receiver module is represented here by IRRX, powered from a 5-Vdc supply. An infrared ...

The infrared receiver VS1838 (IRRX) hardly requires external electronic components. However, an RC-network ... it’s very easy to build an Arduino-based IR universal remote that will record infrared ...

If you’ve ever needed a short-range remote control for a project, [firestorm] is here to help you out. He put up a great tutorial on using an IR remote to do just about anything with everyone… ...

Hello, I have recently purchased a new 65in 4K LED TV and connected it to my existing home theater system. I have all components in a closet and am using a Xantec 789-44 IR receiver. There are 4 ...
