/*---------------------------------------------------------------------------------------------

  Open Sound Control (OSC) library for the ESP8266/ESP32

  Example for receiving open sound control (OSC) messages on the ESP8266/ESP32
  Send integers '0' or '1' to the address "/led" to turn on/off the built-in LED of the esp8266.

  This example code is in the public domain.
