IR sensor tuned to 38KHz, perfect for receiving commands from a TV remote control. Runs at 3V to 5V so it's great for any microcontroller
To use, connect pin 3 (all the way to the right) to 5V power, pin 2 (middle) to ground and listen on pin 1. It doesn't do any decoding of the signal, just passes the 'raw data' along. Check the TSOP38238 datasheet for more details
Adafruit has a detailed tutorial with example code and wiring diagrams showing how to read from a remote control, make a intervalometer, and more
