/*
  Passing paramters to Ticker callbacks

  Apart from void(void) functions, the Ticker library supports
  functions taking one argument. This argument's size has to be less or
  equal to 4 bytes (so char, short, int, float, void*, char* types will do).

  This sample runs two tickers that both call one callback function,
  but with different arguments.

  The built-in LED will be pulsing.
