Adafruit IR (Infrared) Receiver Sensor

The IR sensor, finely tuned to 38KHz, excels in receiving commands from TV remote controls. Operating between 3V to 5V, it seamlessly integrates with various microcontrollers.

Connect pin 3 (rightmost) to a 5V power source, pin 2 (middle) to ground, and receive data on pin 1. The sensor transmits raw data without decoding the signal, allowing for a versatile range of uses.

For detailed operation, consult the TSOP38238 datasheet. A comprehensive tutorial is available, featuring example Arduino and CircuitPython code, complete with wiring diagrams to facilitate remote control reading, intervalometer creation, and additional applications.
