Pins definition moved out of constructor.

Warning! This version breaks compatibility with older sketches. Pins definition was moved out of the constructor (spring 2019).

Working version, before the 2019 spring cleaning.

Pins are defined in the constructor, which may cause problems on some architectures, see the most recent documentation.
