[arm-allstar] RGB LED RPI

[TomXtal]

Thanks for your input Doug. I have watch a youtube of Peter Kendall 
G7RPG of his micro node www.youtube.com/watch?v=CTIgOlsq9jI which uses a 
status LED, this is what I'm trying to do. I can see it is wire to the 
GPIO pins but I can not see which pins are being used.
