Howto: Controlling Pine64 GPIO via the filesystem (sysfs) on linux
#4
Very good guide! It has given me an idea for a project - a switchable backlight for the Pinebook keyboard. This facility is available on some more expensive laptops but would be nice to see on the PB.

What would we need:

Physical fitting of LED(s) within the keyboard mechanism
Facility to switch an LED on as descibed above
Allocation of a function key to control this

Of course the effect achieved will depend on the transparency of the keys, we might just get a glow round the edges. An alternative, which I have also seen on some laptops, is an LED placed near the webcam shining down on the keyboard. Some ideas anyway!
