// try to parallel processing on arduino like plumbing
// plumbing is more elegant,
// but its possible to do basic stuff without plumping on arduino using Alarms/Timer libs

breadboard setup

in this basic example,
three LEDs are blinking..
with different on/off times,
and one button,
pushed all LEDs will be switch on


#include <Time.h>
#include <TimeAlarms.h>
