Task 9 - LED blinking but mostly ON

/*
*Blink2_ON_off
*Turns on a red LED on for most of a second, then off for 50 milliseconds, repeatedly.
*It also does the opposite to an off-board LED connected to pin 12 so that when one LED is on the other is off.

*The circuit:
* A red LED connected from digital pin 13 to ground via resistor.
* A yellow LED connected from digital pin 12 to ground via resistor. I used 220 ohms,
* (I think - they're so small I can barely read the colours: JMH).
* Note: On most Arduino boards, there is already an LED on the board
* connected to pin 13.
* Created 1 June 2005
* By David Cuartielles. Adapted by Peter Brook (& Jane-Maree Howard, 25feb2010)
* based on an orginal by H. Barragan for the Wiring i/o board
