New member here. Also new to RPi, but have a fairly good knowledge of arduino.
I'd like to set up my Pi as a media centre, and have settled on OpenELEC based on reviews. I'd like to connect a couple of things to the GPIO pins, to act as inputs and outputs (I'd like to integrate an on/off button and a more powerful indicator LED), but I'm really struggling to find out how to add GPIO code to the OpenELEC build.
I'd really love some advice, if anyone is willing. My coding skills are limited to Processing so far, so I'd appreciate it if you could tailor your advice to bear this in mind!
