Word Bits

Can anyone explain to me why I get "error: 'B0000000000000000' was not declared in this scope" for

word LED = B0000000000000000;

Because as far as I can tell, I am declaring it. This is before the Void Setup()

Because the B notation is #define’d in the Arduino language and only works up to 8bits. Use the normal C notation and call it 0b0000000000000000 and it will work.

Better still, learn hex.
Long binary constants are a brain-ache.

Hmm Hmm... Ok Thank you very much!
