Why use int instead of byte?

CS Purists didn't like it because it wasn't typed. I claim it never needed to be typed...

Either that or the long list of macro related failures tends to lean us away from #define. (I helped someone with such a problem just this week. Fortunately the problem was trapped by the compiler.)

Add your #define to this snippet...

void BlinkIt( int LED )
{
  for ( int i=0 ; i < 10; ++i )
  {
    digitalWrite( LED, HIGH );
    delay( 250 );
    digitalWrite( LED, LOW );
    delay( 250 );
  }
}

Use a typed constant instead. Trouble averted.

(better NOT typed than WRONG typed?)

Has merit.

const byte LED = 1034;

void setup() 
{
  pinMode( LED, OUTPUT );
}

void loop() {}

No warning or error. Ugh.
