Q1) How
can I find the latitude and longitude of my location?
A1) Open a Linux terminal and at the prompt type
“python” and hit the <ENTER> key, then type in the
following:
city = ephem.city('Vancouver')
print city.lat, city.lon
or
print city
Will print all information know about that
location.
Choose a city that is close to you if yours
doesn't exist and your sunrise and sunset variables will probably be
close enough. You can get your exact Latitude and Longitude from
Google maps by pinpointing your location.
Q2) How
can I have a generic interface into the system.
A2) You can use a “NamedPipe” interface for
example a piece of camera equipment that we don't have the code to
echos a "motion" to a UNIX style pipe file. We can read
this file and if we assign it as a “StateInterface” device and
use a “NamedPipe” Interface the system will know if it is
“motion” or “still”.
pipe_front_yard_motion =
StateInterface(NamedPipe('/tmp/front_yard_motion'))
