Array Basics (sizeof)

And just to satisfy your demands here is function that takes a reference to any size array :slight_smile:

template< typename T, size_t N >  void Foo( T (&t)[N] ){
    Serial.write( t, N );
  }

And the pointer version

template< typename T, size_t N >  void Foo( T (*t)[N] ){
    Serial.write( *t, N );
  }

And if you look closely there is no need for sizeof to get the length.
