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.

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 ...

A single seven-segment display might not be extremely useful, but with [firestorm]’s tutorial, it’s easy to give your Arduino some remote control capabilities with a simple IR receiver.

The combination of an Arduino with an IR receiver will allow the sock to send the signal to the TV. This can be programmed for 'stop,' 'pause,' or the power button, depending on TV capabilities ...

I have a friend with an old kenwood reciever that does not work. I want to gut the case, and build a computer inside. I was thinking about putting an IR reciever in, getting a card for lcd control ...
