[vc_row][vc_column width=”1/1″][vc_tour][vc_tab title=”Introduction” tab_id=”1394073451-1-88″][vc_column_text]Breathing light is a status light really, also used for notification if a new message arrives or perhaps if you missed a phone call. you might want to consider turning it off if you are concerned with battery life as it does use a bit more, tho i am not sure if it is that significant.
I have published a post about breathing light- using arduino board, but use on pcduino ,need some modification.
