Sample GPIO codes highlighting RPi.GPIO-PineA64 and the PI bus

[tllim]

The above pic is an updated photo of the LED lab ;  the white 4bit bus is coming from the euler bus, the blue 8bit bus is coming from the PI bus in a two row configuration.

Each pair of blue LED(s) has a common cathode;  the resistors drive the anodes across the bread board divide where they meet up with the 8bit bus from the PI-bus. 

The LED(s) patterns have a different visual effect arranged in two rows of four, rather than a single row of eight(8).

Appreciate and thanks on the tutorial
