IR Transmitter

/*
  BuiltByTyler Sensor Kit - S13 IR TRANSMITTER (940 nm LED)
  Board: ESP32-WROOM-32 DevKit V1 (30-pin), Arduino-ESP32 core 3.x, "ESP32 Dev Module"

  Sends a NEC TV-remote code every 3 seconds (aim the LED at a TV).
  Use the S12 sketch to read your own remote, then put its address and
  command below. The library makes the 38 kHz carrier for you.

  Wiring (module pin -> ESP32 pin):
    GND  -> GND
    VCC  -> 3V3
    IN   -> GPIO 18

  Library: "IRremote" by Armin Joachimsmeyer, 4.4 or newer (needed for ESP32 core 3.x) (Sketch > Include Library > Manage Libraries)
  Serial Monitor: 115200 baud
