Decoding the World Around You: An Introduction to Arduino IR Receivers Infrared (IR) communication is everywhere, from controlling your television to operating your air conditioner. At the heart of ...

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.

We’ve featured loads of IR Arduino projects and they are all exciting and unique. The projects spring from a specific need or problem where a custom infrared remote control is the solution. [… ...
