LED Project - due 12 March 2010

* In this project, i use a 3-colour LED
* and first turn them all ON, then OFF.
* Then i successively blink the RED, GREEN & BLUE
* LEDs, each with the same delay time, which ramps
* from 10ms up to 300 millisec & back down again.
* Here i use two 'for-loops': one to ramp up the Delays, &
* the other to ramp them back down again.

* Loop first turns all 3 LEDs on succesively,
* then turns them off again.
* Delay between each phase is about 100 milliseconds
* Loop now turns RED, GREEN & BLUE LEDs on & off
* cyclically with varying delay each time loop runs, &..
* ..repeats endlessly while Arduino has power.

* I hope (!!) to post a video of the project running (soon)

* At the half-way point the order of the LED-cycle is reversed;
* Viewers could try to spot this point!
* What indicates this?
