A new guide in the Adafruit Learning System: Building an Infrared Transmitter and Receiver Board
Most remote controls for your TV, cable box, Blu-ray player or other consumer electronic devices use infrared signals. IR is also an inexpensive and effective way to control a variety of maker projects. IR is especially useful in creating assistive technology devices for the disabled, such as mouse and keyboard emulators.
The device consists of 2 infrared LEDs driven by 3 transistors as well as a TSOP38xxx receiver chip and a TSMP58000 learner chip. We’ve even thrown in some extra ground and power pins that makes it easier to integrate this board into your project.
Full open source code is provided to work with IR signals in Arduino.
