Blink & Button Objects - WIP

i starting move demo projects c++ classes. haven't messed classes since 1999.

but works far ioblinker class blinky led objects , iobutton class make button objects. buttons debounce. sketch reads button find output state may -1=undecided, 0=off, 1=on, 2=changed off since last read, 3=changed on since last. sketch doesn't need remember last read, it's taken care of states 2 , 3.

in future plan add other demo interfaces classes, including serial user io.

but need advice. want stick arduino ide if add library files in ide change , save them, save in sketchbook folder instead of ide library folder. open editor, more work me.  

and here's (already improved) demo. requires arduino , 2 jumpers or buttons.
now added setpin function led object , demo goes buttons array.

code: [select]


// ioclasses demo io_events_2  dec 21, 2014 goforsmoke
/*
  sketch uses 2 classes ioclasses.h make led13
 blink , grounded jumpers on pins 6 & 7 control rate.
 ground pin 6 , rate adds 100ms. pin 7 subtracts 100ms.
 
 button output state value use in sketch code.
 -1, undecided, pin state changed @ least debounce-time ago.
 0, button still not pressed.
 1, button still pressed.
 2, button released since last checked sketch.
 3, button pressed since last checked sketch.
 the sketch doesn't have track previous output state.
