	The ~~first half is changing the circuit; the other half is changing~~ the ~~logic. The built-in Arduino~~ blink ~~program is useful, but not particularly graceful. It shows us how to toggle the voltage, but it's a bit clunky in how it implements the library. Here it is:~~		The following Arduino sketch will make the LED blink:

	This works, for demonstrating how a blink circuit works, but it'd sure be nice to have a Morse Code library and make that code more compact and graceful.
