+	//	1.	Led turns off and stays off for a long delay.
+	//	2.	Led blinks x times with a short delay, where x is the current
+	//		decimal place + 1 (so 0 values are easier to see).
+	//	3.	Led stays off for a long delay to indicate the move to the next
+	//		decimal place and step 2. is repeated until all the rest of the
+	//		number is 0.
+	//	4.	The led turns on and stays on with a long delay to indicate finish.
+	//	5.	Led state is reset to the original value.
+	//
+	// The lowest decimal is output first, so the number will be reversed. As an
+	// example the number 205 would be blinked as follows:
+	//		long off (start indicator), 6 blinks (indicating 5),
+	//		long off (moving to next decimal), 1 blink (indicating 0)
+	//		long off (moving to next decimal), 3 blinks (indicating 2)
