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.

Arduino IR receivers offer a simple and affordable way to interact with the world around you. By understanding the basics of infrared communication and using the IRremote library, you can easily ...

After uploading the IR receive demo included in the library, the Arduino spit out hex codes of what the IR receiver was seeing. [firestorm] wrote these down, and was able to program his Arduino to ...

In this project we are introducing a simple IR receiver circuit and code that will allow you to integrate remote control function to various projects using the ATtiny85 microcontroller. Following is ...

After some searching, I ended up using a microcontroller and a piece of code borrowed from the web that I tweaked and adapted. The microcontroller-based concept was chosen because I wanted to scale ...
